Mobile nav not showing when halfway down the page

Design help General

Hi all,

I have a site ive built to which the mobile nav is on the bottom of the screen.
When I scroll halfway down the page and tap the hamburger menu, the screen is blank and i have to scroll all the way up to see the nav links.

Any one have any suggestions on this?

Thanks

Hello Ben

Just switch the positioning on ( Nav Menu 2 ) from Static to Fixed, That will fix the issue.
