I think I know what was causing this or at least part of the problem.
1) It seems like the new version overwrote the previous version’s “size of image”. If you are not aware of this and/or don’t remember image size that you used in previous version it is a bit of a problem.
2) When you uncheck Display Titles Under Images in order to get them on top then no titles appears which causes all images to be displayed with no titles and all squashed up together.
3) It seems like some of the warnings that I know get on each page seem to be related to these issues although I could be wrong:
