Advanced Editor Losing some page design on save

Hey when we hit publish on the page design, the first time we add in new elements using the designer it will save, but if we go back and edit ANYTHING on that page. It will lose some, not all, but usually the new stuff on the page.

So for example, i add a new color section, two 1/2 splits with a google map in one and a text box in the other, after creating these it will save.

But if i go in to edit the text in the text box, or any of the other features on the poage when i save the whole color section and everything in it dissapears.
