Serviio

I am running Serviio 1.1 as a new install. Everything seems to work correctly except for the listings under "Album Artists" in the Audio section. For some reason it lists everything under "U" for Unknown. My question is, is there a way to to force Serviio to reindex these or do I need to manually update the database? When I had looked in there, it looked like all the information was present, just not referenced correctly.
Thank you for your help with this.

Try to move one of the files to another folder to force reindex. Also, try with 1.2

I tried moving files out and back in with a forced refresh in between with no effect. Then I upgraded to 1.2 and tried it again. Still no change. I did a manual update to the database and then forced a refresh. That did work.
