Missing albums.

I'm using version 7.7.2, the latest available for my Synology NAS.

Here is just one example.

If I search for the artist Underworld here is a portion of the albums listed including the Batman And Robin Soundtrack. So far so good.




If look into the music folder I see the album. OK.




If I search for Batman, the album is not included in the result, though ironically a song from the album is.
