Elementor – Hamburger menu not showing up on some pages on mobile

I’ve noticed that on a couple pages on my site, the hamburger menu isn’t showing up on mobile, but it does for all other pages. Here are the 2 pages I noticed that it doesn’t show up:

https://ofrspto.org/
https://ofrspto.org/mission-and-values/

Can anyone help? I’m at a loss as to why it would work on some pages but not others. TY
