Series sorting issue (when folders are empty)

Thanks for the great app. It looks beautiful. Even better now I updated the favorite tile background images.
I bought the Pro update primarily because it works well with AC3 audio.

One of the issues I have found so far is that certain series were not sorted correctly when fetching metadata
After alining some foldernames with the series names (from the tvdb) most of these issues were resolved.

However, when fetching metadata, empty folders are seen as errors and the folders remain at the top of the overview.
Folders are empty because I do not keep episodes after I watched them, but I do keep the series folder while the series is ongoing.

Please change the metadata fetching procedure so that empty folders are handled the same as all other folders.
