I believe I am seeing the same thing or something that might at least be related. Im seeing it in the in-page slider options. If I change image, add stlye options, links, or heading it dosent change when I publish the changes. It just reverts back. I assumed it was a plugin issue but I have disabled every plugin not directly tied to the theme and it still does it. Oddly I only see this on pages with large amounts of content.
