Object Reference error

I'm trying to import a PowerPoint project into Storyline 3. It imports fine, and I'm able to make changes to the slides, but when I try to save it I get the error message, "Object reference not set to an instance of an object." I've tried importing the slides one at a time, and I'm able to save when some are imported but not when others are. If I delete the slide that's causing the problem, it allows me to save the project.
