Sync Problems

Hey all,
I cannot delete old contend of my PlexSync. :-S

What i have done:
- Deleting old Servers unter Settings -> Devices -> Servers.
- Deleting old Cloud entrys in Plex.tv -> MyAccount -> Settings -> Cloud Sync.

However, old shows are displayed in cloud database,
there are Deleted, if i click on it, there is an error, file is not accessable. 8-|

Its also looks like, that new media isnt showing in CloudSync.

Any suggestions?
