Anime and Animation Genre not showing

Hello!

I'm in a strange situation:

Before installing and using Anidb.net scrapper I've an Animation category in Movies section, but I hadn't shown anime movies and chapters.

After installing Anidb.net scrapper and using it for "anime" folder/source, that scanned all my anime (at least I've seen it), I've no anime in Movies and TV Shows section, and the most strange, I haven't Animation category now.

Any idea about what's happening?

Thanks in advance!
