Mobile Navigation Menu text is white with white background

Hi guys!
This is my first time posting on this forum.

I have encountered a problem where I am using a transparent header (created by me), created using the theme builder in elementor pro.

I am using elementor pro, and the header was only created using elementor pro (I have tried going to customize->header, but I can’t find anything there that might help me.

On the home page (desktop) it appears fine, just exactly how I would like it.
However, the problems occur when I try to access the navigation menu on mobile.
It will become evident that it is just a white on white navigation menu (drop down).

How can I fix this?

I have no experience doing CSS, or anything like that, though I suspect the problem could be fixed going that route.

I hope I have been clear in identifying and portraying my problem to you guys.
Thanks a lot, and I appreciate any guidance that you kind people offer me.
