Characters appear to move after publishing

Hi!

I have an Articulate illustrated character I'm using in a course I've been working on. Things have been fine throughout the process until I went to publish an updated version earlier today for review. On two of my slides, she is supposed to appear in the bottom corner, while bullets fade in. When I publish, she is suddenly taking over a much larger portion of the screen, covering some of the text. I've tried moving her over further and shrinking her down, but it seems she keeps popping up in the same spot after I publish. Any ideas on why this might happen? It's just so odd this is only happening now, after six months of working on it.

Thank you!
