Changing Header Size

I have a header that I have designed as a mega menu on the desktop breakpoint with drop-down containers that appear on hover. I am trying to design a traditional hamburger menu on tablet and mobile because the mega menu is too big for those breakpoints.

When I try to change the header size on those two lower breakpoints, I make the change and it just does nothing. I have done this twice before with no problems. Does anyone know if there is a technical issue or if a setting got changed to where you cant change the heading size on different breakpoints? Here is a screen shot of all three Breakpoints:

Desktop:


Tablet:
Here I changed the header size to 20px and it stayed at the original 150px, even though it says it changed.

Mobile:

Hi @bradlee-thornton , we took a look at your site and it looks like the headers are working correctly. Are you still experiencing the problem when you view?

No, you are correct. There must have been an issue because the next day I was able to change the header size again. So I finally got it, thanks!
