Can anyone help me move my navigation to where it should be

I have a problem with my custom code for my navigation. I have used this code on a couple of sites and it has worked well.
On this site it works well on About and Video pages but not on Home page. Nav ends up in lower right corner even though it is a css grid site.

Here is my site Read-Only:
And published:

Please add a screenshot of the problem (Hard to understand your issue).

  • Add URL for the good URL & Bad (No menu in your site).

except that in this version you can not click on video in the bottom right corner (on desktop)
