Serviio

I use Serviio 1.0.1 on MACPRO (MAC OS X Mountain Lion last update). Serviio is configured for autoupdate its media database every 15 minutes. As a rule I access my movies via "Folders". The problem appears when I rename one of the folders in my medialibrary. After that I can see two folders on my mediaplayer with old and new name. I try to update media database by pressing corresponding button in Serviio Console but nothing was corrected. I think that the only way to correct database is to delete shortcut to my medialibrary folder in Serviio Console and register it next time.
Is it the bug or feature of Serviio?

It's a feature, it might take up to 1 hour to remove the original db entry.
