Extra taps on mobile iOS menu items

Hello – when I view the template on my iPhone, I tap the hamburger menu, there are extra taps that make the menu items underline rather than function. The first tap creates an underline, then I have to tap again to go to the page.
To reproduce the problem on mobile:
1) Tap the menu
2) Tap .Portfolio, the underline appears but no dropdown
3) Tap .Portfolio, the dropdown appears
4) Tap logo design, it just shows the underline
5) now you can tap logo design again and the page finally opens.

This entire thing should be 3 taps but it is 5.
