'Current' state not visible in mobile

Hi all! I am trying to edit the current state of my nav links in mobile breakpoints (with the hamburger menu) as the text size is too small - however, I can’t find the ‘current’ state. I can get the current state in the desktop breakpoint, but when I apply the same logic to access this in mobile, it won’t show up.
I hope I’ve explained this OK…

Really appreciate any help!

Here is my site Read-Only:

if you have an element that’s selected and that SHOULD have th Current state, then use the keyboard to navigate away and back on the element. Like just do up arrow down arrow. the Current State should appear.
