Video won't play on top on mac version of Captivate 2019

I have a PC version and mac version of captivate 2019

In the mac version an identical slide doesn't work properly.  The video is behind the background of the slide whereas on the PC version it is in front where it is meant to be.  The video is on the top on both slides.  But when i play it in preview or in HTML 5 browser the video isn't visible except for it's very top edge when playing the mac version.

I closed the project, reopened it in the PC version, closed that and reopened the mac version, and now everything is working perfectly.  Must have been some glitch.
