[Hustle Pro] White bar under the videos

Hello,
I recently noticed this: There’s a white, horizontal bar under the (YouTube) videos on our pages. I checked it out and it says it’s originating from the Hustle Pro plugin (although, it could simply be reacting to another plugin, or vice-versa).
Please see attached for an image of the white bar.
A page that has the white bar can be found here.

Thanks,
JL
