After Effects Layer bars not showing up on part of Project
I started a project in school in after effects of a lyric typography video. I’m about 2/3rds done with it and I was revising some layers towards the beginning but I noticed that about the bottom 100 layers the bars that mark when the footage starts and stop have totally disappeared. They still retain all of their settings and still turn out in the final preview, but the boxes aren’t there to shorten or shift the particular layer. I’ve right clicked menus and selected things looking through and nothing seems to have any effect or setting on this. I’ve done some googling but Haven’t found any answers yet. Any help would be appreciated. Attached is a screenshot where the bottom part shows the missing ‘bars’ and the top you can see a few of the layer bars. I can post additional screenshots or files, etc. If needed.
Thanks in Advance,
