At one point after this thread began, the MS Word program closed suddenly and unexpectedly because Windows 10 wanted to do an update (I was quite displeased about that). Anyhow MS word created a repaired version of the file the next time I opened it. And now, I just went back to the problem page, and I am seeing that the program has fixed the issue and there is no longer any page discrepancy. So whatever was the cause of the problem, it is now resolved! Thanks very much for both of your help. I hope I don't face it again going forward-- will let you know if I do and maybe we can solve it then.
