"Combine Multi-disc album" not working

[ARDEACT]

I accidentally turned this option and my library blew up, I checked it again but the albums aren't combining.

Hi,

This option doesn't change anything to the metadata of the files, so if you turn it off, you will get back the previous behavior. You can also try to restart foobar.
This option works with the tags %totaldiscs% and %discnumber%. Default behavior is "If totaldiscs is greater than 1, then group separately the tracks having a different discnumber". When the option is checked, it doesn't look at those tags, so it will group all tracks having the same %album artist% and %album% tag
