Technical Help, Heading Not Displaying Properly

I have a site where the desk top version my site displays correctly but in Portrait Mode the H1 is hidden at the top left. Also, my Top Nav Bar does not show only the navbar at the bottom of the page and this is only on Mobile. All my issues are on Portrait Mode only.
Here is my read only link if this helps:

Thank you for the help,
