One on a page loads up fine. When I try to add a second, with a a few horizontal Ruler's between it disappears.
After you save all changes, it is no longer in the list. I have one with 4 in it and one under with 5 in it. I can get it to stay if one slot is left blank. For example the Logo/Partner List has four logos and Logo 5 is blank. If you delete the blank logo 5 it disappears.
I know it sounds like "it hurts when I do this" so the doctor tells you to stop doing it... However, I spent an hour on finding the workaround, thought it may help others.
