First Page/Word in Nav Bar Glitching in Mobile Mode only

Hi there! I bought a website template and I am having trouble with the navigation menu in the mobile breakpoint! I’ve checked everything from top to bottom and I just can’t find why the first page/word shown in the Nav bar lights up and goes off, just to light up again in mobile mode. I don’t have this problem in the desktop breakpoint. I would really appreciate some help :slight_smile: Thank you!
