White Spacing above Embed Youtube Video in Module

Hello there!

I am creating a blog post which includes a written article and a video underneath. I added a new module for the embed video and everything looks fine until I hit publish, at which point it adjusts to have a large white gap between the article and video.

I checked margins on both the text and video modules- is this a known bug or fixable? I would love help!
