Working in XDP X version 19, on a windows 11 Pro.

I’m sure this is something really easy that I am missing. Here is a current website.

https://draft-review.com/

In the mobile version, in the header, I added an arrow pointing to the navigation menu. The arrow does not display on preview.
If I move the arrow down on the page out of the header, it does display in preview.

I’m checking my page and layer gallery, it’s in the mouse off layer.
Can someone please give me direction as to how to get that arrow to show up in the header?

Many thanks in advance for your help.
PS Tried to upload my XAR and it hangs up; tried zip and at 154 MB still hangs up.
