Woodlands Court in New Springs, has been accidentally rated inadequate by the Care Quality Commission after an 18-month-old report was re-published on the site this week.
The home was previously in special measures in 2017 before redeeming itself in an inspection back in March.
However the most recent report to be published on the watchdogs website includes concerns about residents sleeping in rooms with soiled mattresses, a problem care home bosses say was solved more than a year ago.
A spokesperson for Woodlands Court said: The report relates to an inspection carried out by the CQC in June 2017.
A new manager was appointed and they worked closely with our regional management team to improve procedures, the standard of care provided, and the physical environment of the home
Staff numbers have been increased and all new and existing staff have undergone rigorous training.
Amid the old document are details of an incident in which one patient was left to wet themselves in the corridor, an incident which occurred long in the homes troubled past.
The report also includes comments about dirty slippers and personal equipment, and incorrect medicine management which put patients at risk of harm.
The homes spokesperson added: Feedback from residents and their families points to noticeable improvement in the 18 months since the inspection was carried out.
A filthy care home where residents were found with unexplained injuries has been put into special measures.
A damning report by the Care Quality Commission exposed multiple failings at Saxon Lodge in Bridge, including broken toilet seats, foul-smelling furniture and unhygienic facilities.
Inspectors, who made an unannounced visit to the home in August, found carpets in a bedroom and hallway were so filthy, they stuck to peoples feet as they walked on them.
They also saw tiles had fallen off a wall, sharp pieces of plaster protruding off the walls and a stained and dirty wash basin, although bosses had stated no improvements needed to be made in an audit just weeks prior to the visit.
In their report, inspectors also highlight serious shortfalls in safeguarding people from the risk of abuse after records revealed two people had sustained unexplained injuries on five occasions between May and August.
Indeed, one of the entries described the person as having sustained multiple bruises, it reads.
We asked the registered persons what action had been taken to notify the local safeguarding authority about these injuries.
We were very concerned to learn that neither of the registered persons were aware that the injuries had occurred and as a result they had not made any enquiries to establish what may have caused them.
Inspectors also raised concerns about low staffing levels, residents not having enough to drink, risk of infection, and numerous defects in the home, including broken blinds, stained wallpaper and no light shades in bathrooms.
Five members of staff were asked about their experience working at the home in Western Avenue, which cares for 23 older people, some with dementia.
One said: The morale in the staff team is desperately low, largely because there simply arent enough care staff on duty on most days and thats the case even with the manager working flat out.
Despite residents stating they felt it was a caring place, one admitted staff are rushed off their feet.
A CQC spokesman said as a result of the continuing breaches of regulations, the overall rating for the service is inadequate, putting the home in special measures.
If not enough improvement is made within six months and there is an inadequate rating in any area, enforcement proceedings will begin to prevent the manager and director of the home from operating the service.
Saxon Lodge manager Christine McArthur said: Whilst we were disappointed in the report from the CQC, we are working closely with the CQC, the local authority and an outside consultant to move the home forward.
We continue to be committed to improving standards and to providing a safe and caring home for our residents.
