File Monitor - already exists error

File Monitor - already exists error

I deleted and re-discovered some servers, in order to get the "installed software" populated.  Now I have a problem, building back in the File Monitors which I had built under the server.
 
I have no FileMonitor Templates built.  When I try to create a new file Monitor, opmanager errors, stating a File Monitor already exists with that name.  So apparently the individual file monitor, which previously was built under that server, did not get cleaned out of the database, when I deleted the server device.  Opmanager has no capability for me to retrieve that monitor and add it to the new device which i've built.  
 
I would like:  Opmanager not to leave remnants of old adhoc file monitors in the database, unless of course, it has the capability of selecting that old monitor (it does not).  The adhoc file monitors I'm using currently can not be a template as they are individual, and never exist on a different server.
