I have one of my image galleries set up to show the images on another page. Works fine except I can't edit it now that I have it created.

I created this before the last update and now I can't change it. I am trying to change it so that it displays 7 images instead of 8 images. When I submit the edit, I get back the following control panel message:

Help!
