Container (video, picture, normal box container) goes over section border in stretch mode

I’m having trouble with
My video box (or container, happens with both) is flowing over the section border when I have it in stretch mode (see screenshot). I need to have it in stretch mode in order for it to be responsive. I have padding in the section but behaviour shows also on 0 padding. Yes, I checked the sizing it’s set to 100vh height, others are on auto/none. This happens all the time btw, on some days it’s stretching properly, on some days not.

Working in
Wix Studio Editor

What I’m trying to do
I want the freaking (video)box to just stay inside the section’s borders

What I’ve tried so far
I think it’s happening either because of padding or height settings, idk I tried everything, happens every 2 days
