Cant remove old "Search Field" frames

Hello again gang… I am working https://www.fishingpierinc.com with the Platform theme (not pro version)

I removed the search bar in the menu field. However, I believe the framework is still there, Immediately to the right of the “reach us” tab
When I include an additional menu link, it places itself just below the “home” tab.

When looking at the style sheet…. I am only shown a few lines of code, nothing specific, with this include:

“Don’t add it here; as it will either get overwritten by updates, or prevent you from updating at all”

Any advice on how to remove the frames?

Thanks!
