Kodi scanning folders for media that are not configured in my sources?

Hi there

Kodi whilst doing a library update/refresh has been scanning directories on my NAS that it is not configured to do so.

i.e. smb://NAS-NAME/TV/ is configured but instead it just scans one level lower (the root of the nas path) smb://NAS-NAME/ and starts picking up a whole host of folders like admin, backup, c, and then starts adding a load of crap to my library. Is there anywhere I can find out how/why it is doing this?

Any help greatly appreciated.

Thanks

Dan
