Cannot Access Current State

Trying to access the current state on my nav links but the state is not accessible. I navigate to the correct page and the nav link is shown in blue but no ‘current’ class is shown?

Share only link below, any advice appreciated.

Here is my public share link: [LINK]1

Would you be able to try access the ‘Current’ state through the navigator without opening the hamburger menu?

Yeah that’s done the trick, thanks.
Surely most people would open the menu, click the link to try and style it? Not sure what’s going on there but stoked for your help!
