Double vertical scrollbar on Jasper template

I've never had this problem before, but how do I get rid of it?

Yep, I noticed this too. Messes up the scrolling action as well.

It also does it on mobile too.

What the heck Squarespace?!

EDIT

I think it has something to do with Google Chrome. I opened it up with Microsoft Edge and it's no present, although...the dual vertical scroll bars did appear for a short second or two. Weird!

SOLUTION:

Add this to your Custom CSS:

.overflow-wrapper {
overflow-x: hidden;
overflow-y: hidden;
}

I added this to my CSS and it did the trick:

.overflow-wrapper {height: 100vh;}

i seen this too, did you find ay to fix?

The code above works!

Thank you! That worked.

Sorry, I actually noticed that this also got rid of the submenu at the bottom of the page. Any way to fix that?
