More Albums showing with latest Update?

[glainc]

I'm not aware of any of our files or folders starting with a period. Not something I've ever seen.
But here's one example, which is representative of the entire library.
Folder Claire Martin > Too Darn Hot
Tracks:
01 - Something s Coming.flac
02 - Love At Last.flac
etc.
ending with Folder.jpg for the cover pic.
I checked the tags too, and nothing begins, or ends, with a period.
But the album appears twice. And each is identical as far as I can tell.

When I Choose Verbose logging and Rescan, I get only this in the window:
restarting MinimServer[QNAPmusic]
starting MinimServer[QNAPmusic]
MinimServer[QNAPmusic] is running

As I mentioned before, many are shown doubly, but the cover pic appears with only one of the two instances.

Can I revert to the previous version?
