I created an interactive PDF, comprised of buttons that show and hide each other accordingly. It was all working fine in the previous creative round, then a couple images were added. They becomae buttons and after that, the PDF has never displayed the buttons in the proper order. The Object > Interactive > Set tab order... is set correctly with the levels the buttons should appear in reversed order. I even went as far as to turn all the buttons back to objects, then into buttons again, created in the order I wanted them to appear (the bottom-most buttons created first, and the top-most buttons last, then set in the tab order panel correctly).
When I click on the first button to reveal the next layer of the content, the button jumps over the content it revealed, and similarly with the next botton. Each button stays on top of the next revealed content, and has persisted through tab orders set in InDesign, and in Acrobat. It was fine before I added the last couple images. Thoughts?

I'd suggest cross-posting in the Rich Media Acrobat forum.
