Missing Content in Track View - BUT Audio still plays

Has anyone run into this? I have a few tracks in a project that aren’t showing the recorded content, but the audio in those tracks is playing just fine.

The weird thing is that the tracks do all show content in one place, but all at the same place. These particular tracks are crash cymbal tracks, so obviously, each track should be showing different cymbals at different times.

It’s only cosmetic, but I’m wondering if anyone else has experienced this. It also seems to be currently limited to this one project - and this project did previously show the content properly.

Thanks in advance for any help!
