Display Updates not Saving

Hi,

I am trying to edit an already created hustle slide-in, however the changes I make are not saving. I am unsure of how to troubleshoot this issue. It should also be noted that the slide in does not display in the correct format that it is set as.

The popup is configured to display on blog pages like this one: http://24kcreative.com/2016/11/21/your-questions-about-retargeting-answered/
