Videos Resizing

Hello,
I am updating videos on a site that I manage (did not build) and all of the video components have turned into square aspect ratios when I save the changes. When I am in the builder, they appear correctly. Any help/thoughts would really be appreciated. Screenshots below. The first shows in the builder, the second shows when browsing. Thanks.

 

Thank you for the response. Here is the page in question. https://www.drfrazar.com/dental-videos/

Appreciate your consideration.

 

Thank you. I will give that a try. Honestly, I have not edited the code on the site, I manage the content through the front-end editor so I am certain I know how to implement this change. But I do appreciate the help.
