I finally stumbled onto the solution to my problem, though I still don't know what caused it. If I go to the bottom of my repeating section and click Delete, my extra spaces disappear in Preview mode. The strange thing is that when I click Delete, nothing changes in Design view because nothing is there to delete. The fact that these forms used to lack the extra spaces and I have done nothing to them since then, and the fact that all of my 50 plus forms now have this new problem reinforces my belief that I did not cause this to appen. I wonder if the latest updates could have something to do with this? Thanks, everyone, for your suggestions. If anyone figures out what causes this problem, please let me know. Thanks again.
