Mobile Nav isn't expanding the height of the nav bar

We have a very simple site and we are using the built in navbar. It works perfectly on desktop but mobile is slightly broken. It works in the designer but when I click the button on a real browser the menu gets clipped at the height of the navbar instead of increasing the height to fit it all in. I assumed this was b/c of absolute positioning but I’ve checked and there is no absolute positioning anywhere so I don’t understand what is happening.

Here you can see the clipped menu bar, there should be 3 more items showing.

Thank you for your time!
