Closed Captions, purple diagonal lines at end of my captions

[lkelly232]

I have been inserting my captions for a while now and the last sentence I want to put in it says there is not enough space between clips, even though I'm setting the input to a time after my clips have already been placed. I get this error screen.

Your captions clip has Danger Stripes at the end where you are trying to add captions to it. Danger Stripes mean that something has gone missing that was originally there. This seems unusual for that sort of clip. If you can pinpoint why then you will solve the problem.
