"Warning" using PopUp with Upfront

Hi,

added the PopUp Pro plug-in and are using the UpFront theme Parrot. When testing I will se the following warning in PopUp Pro:

WARNING: If you change the template associated with this post then any content or changes you have made using the drag and drop Upfront editor will be lost.

Got a little bit scary since we made a lot of effort and work in the UpFront editor. If I add a new pop and change the post is there any risk loosing UpFront work?

Which "template" should I NOT change?

Cheers
