Hello @Evolution447
My apologies for the late reply. I thought I had responded already but it seems like I did not.
I double-checked the code for the theme and the behavior of the menu on mobile was changed to static because the sticky menu would take up too much of the mobile screens height especially when users had uploaded larger logos.
However, you can change this by editing line 1896 of the style.css file.
Removed the following code;
.navbar-fixed-top {
position: relative;
}
