The counter that shows up at the top a cemetery page is very inconsistent/unreliable. What I have found is to go to the photos at the bottom of the page and click on "untranscribed images" to see those not yet transcribed. Even then, it does not always show all of them. There is some kind of buggy code for the various counters used by BG and they almost never are consistent.
I have also found while doing cemetery-wide corrections work, that there are a lot more untranscribed showing in the cemetery map than in that filter window.
You should be able to do your own from the MY PHOTOS and do them in the order that you photographed without having the thing flip you out to a different cemetery. I have not been able to get out and take a bunch of photos of my own, so can't test out what I am saying there.
