Saved project won't keep drawing

I want to have a project saved so users can just open up and pick their camera setup for Zoom - cam 1 full, cam 2 full, or a picture in picture with cam 1 and 2. But the PiP has a rectangle border around it that keeps disappearing from the save file. Its a simple rectangle I made with the draw tool, and sometimes its there, sometimes not.

Also sometimes only one camera will show up, and i’ll have to unplug & replug it to make it appear.

Any help out there? Please and thank you!
