Video moves on screen when published

I have a course that has a few short videos imported into the slides.  In Storyline 2, the videos look fine and are aligned perfectly in the center of the slide.  When I publish the course, the videos are pushed down to the bottom, right side of the screen.  I resized the videos to make them smaller and that did, at least, keep the video controls on the screen but the player is still pushed down to the bottom, right side.  

Can anyone offer any advice on how to solve this issue?  I haven't found anything in the forum yet.  I have tried resizing the videos smaller still and just did another publish to see if that will keep the videos on the screen.

Thanks in advance for your help!
