M4As in wrong order on new Lollipop builds topic

Hi, I've looked around a bunch and haven't found an answer to this, but in the latest lollipop builds, going back maybe a week or two, the music in my library, no matter what app I use, are displayed in alphabetical order. This was never a problem at all and it seems to be only a few mp3 albums that remained in the right order. The track number tags are intact on all the tracks, it just seems as if no app will read them or put them in the right order.
Is anyone else having this problem? I would like to avoid renaming all my tracks with a 01 and 02.

Thanks in advance for help!
