I first noticed this last week. When trying to write emails, I hit a point where one of my elements, usually the last one I added disappears and I can't add any more elements at that point.

This is what my email looks like in the design portion

and this is what it looks like in the review portion

As you can see, the pic that can be seen in the review segment is missing in the design segment. It disappeared when I tried to add another of the same element. I was just wondering if anyone else is experiencing this or if I'm the only one.
