You are correct that I hit the refresh at the top. In fact I barley saw the one on the bottom even after you mention it. I'm sure the refresh did the trick because they all refreshed. I thought at first perhaps they would automatically refresh in due time also, but then I noticed one that had an image of a scene that had a cat tree we moved away days ago, that's what got me going. What does the refresh at the top do if it does not refresh the thumbnails? I guess it reloads the camera list. It seems to have worked (?)
EDIT: I don't really understand. It did in fact refresh all the thumbs, however close examination reveals that all the new thumbnails have the camera date stamp 9/23/2019, when today is Nov 7. Looking at the actual images, I can see by the trash by the driveway and the furniture in the house that these thumbs are in fact quite old.
EDIT 2: Sorry for all the edits. I used the refresh at the bottom and that brought them up to date. Still the situation above in the first edit seems odd.
