upfront added image to 70 pages all at once

I added an image to one page. The image appeared on at least 70 product pages. No I have to go to each page and remove image. This will take a while since upfront loads pages so slow.

This is not the first incident. The previous upfront version overwrote any page I was working on with the content of home. This would happen when clicking the Undo button.

This is very frustrating, We have glitches with every plugin we have tried so far. Been working on prosites for several weeks, resolve one error then on to another.
