Was just looking into this further, I am using a menu anchor for the about tab, if I just use “#about” in the menu, the banner goes away, but that then means the link does not work on any other page than home. If I put the full URL + anchor the banner comes back.
Unfortunately I have done this and the issue still remains.
It does only seem to be on the home page this happens which is weird, if I go to any other page the menu is displayed correctly.
