Editing Live listing pictures is not holding the edit.

Working on and cleaning up revising some listings and this is the second one since yesterday where I attempted and did edit the pictures brightness/clarity finished up showing the edit that was completed and hit revise button and checked the live listing and no changes, same as it was before I edited it...

One listing was strange as when you chose the edit procedure at the bottom, on the far right was a new icon that said "remove background" tried it actually worked...lol but looks hokie for lack of a better word.

Before trying that button I had edited it as well and did not stick with what was edited, but the remove background did work...that icon has yet to appear on any other ones I have been working on.....I will say that the pictures upon creating a new listing are coming up quicker except for pictures 5 or more they still drag if upload at all...and the editing on those seems to be sticking...just the older live listings when revising....hope that is clear lol...
