Woo pages scroll over fixed nav

Hello,

I have a fixed navigation bar at the top of my website that stays with you as you scroll down the page.

Until I installed woo, I had no problems with it.

Now on my woo product pages and cart check out, the page content scrolls over the fixed nav.

Here’s a picture of what I mean https://i.imgur.com/IpG13Ag.png

Any ideas on how to fix this or what could be causing it?

Thank you!
