My mistake, in Event View there is NO data listed.
Tracy, try this:
Make a copy of your project (to protect your work as you experiment)
Does the problem still exist with the copy?
Delete half the tracks in your project. Does the problem still occur with the remaining tracks? Try to isolate the tracks that are causing the problem.
Can you "delete hole" from other places in the project timeline? I.e. try to isolate the specific bars that are causing the problem, or show that any track, any bar, has the problem.
Can you create a new, simple project, from scratch, and still show the problem?
