Unnecessary blank space appears at the top when viewing the modena theme on mobile

[dsds]

Thank you for your continued help.
I installed the latest version of ConcreteCMS V9 (9.4.1) and set up the modena theme, but unnecessary blank space appears that was not there in V8.
As shown in the image, blank space appears at the top on mobile.
There is also a width that was not there in V8 on the editing screen on PC, so is this the cause?

If anyone knows, please let me know.

I’ve tried various things, but
in “Header Settings” of “Modena Theme Options”, when I set “Fixed position header: Make the site header stay at the top of the screen when the page is scrolled.” to OFF, it doesn’t seem to leave any space at the top of the mobile menu.

Is this a bug?
