Track filter is kinda wonky when it comes to audio tracks being in folders or group tracks.
This only applies to the main project/sequencer window. The mix console window filter seems to be working as expected.
- put an audio track into a folder.
- filter out all tracks
- enable filter audio tracks only: Audio track will not show up
- deselect and reselect the visibility for any audio tracks for them to show up with filtering
Same steps goes for any group tracks.
If the audio track is in the new group folder bus, that group folder bus will always show up, no matter the filtering, BUT the audio tracks IN that folder will filter in and out properly.
I am betting the new group folder bus has something to do with it, but I am sure you will get this sorted out.
