In my collection I have multiple folders with music. Each folder is listed in the music library page. The music in these folder is sorted by where the music comes from. So I have one folder with music that I have ripped myself from my own CD collection. I have other folders that contains backups of some of my friends music and other folders containing music from other places.
My problem is that I have two folders that have the artist "A-Ha" in them, and only the albums from the first folder is listed! None of the albums in the other folder is listed.
First I thought it might be due to different case used in spelling. E.g. "A-Ha" vs "a-ha", so I renamed them to be equal (should have been done in the first place) but that did not cut it, so I...
Removed the hypen from both names so that the names was "AHa". By doing so I was able to make albums from both folders show up in the list.
That said. When only albums from one folder was listed, I still could search for "A-Ha" and get listed all songs also from the hidden folder. I also could select the folder for where I knew the other A-Ha albums was listed and get up a list of the reminding albums.
I do not know what other non standard characters what would provoke this same bug. I tried & and _, but they worked wine. Maybe the hypen is special.
Edit: Corrected spelling mistake "a.ha" to "a-ha".
