Mobile menu displays incorrectly on only one page

Hey everyone new here so apologies if a silly question. I have a really quirky issue. The mobile nav menu displays perfectly on every page bar one. Every other page displays it correctly as detailed in picture below. This appears to be android related as it displays correctly on iPhone as pic below. But on the two android phones I have checked it displays off but only on on particular page.

Hi,

Can you share link to page where you have problem?
