Existing Screen Recording Magically Resized...

Hi folks,

I'm updating a scene I created a few months ago. It contains a short screen recording spread out over 5 slides. I updated Storyline yesterday. When I went to make my updates to the scene in question, I realized that the screen recording had been bizarrely resized, and by no clear action of my own. It was somehow shrunk and it no longer fills the slide as it originally did (see screenshot below). I cannot adjust the screen recording size because, apparently, we have been waiting for that functionality from Articulate for about four years. Any input would be appreciated. Re-creating the screen recording from scratch is not going to be easy in this case.
