Black Border around slide

I'm using Storyline 3, and when previewing/publishing my slides have this black border around them. They are thicker and easier to see on the sides (see attached image).

I also notice the entire background is black before the content loads in.

Is there a way to fix this? It looks like it is part of the player frame since the content doesn't cover it up, but I don't see any settings to change that color.

Thanks!
