Mobile Menu Not Linking To Anything

I am having a strange issue while helping a friend with a website.

Everything works fine on an actual computer, but the mobile & tablet versions of this responsive site is not communicating with the menu.

I enclosed a link to a screenshot I took this morning from the back office, this is how it looks on a smart device, and you can see by the image that the navigation menu is the problem.
It looks like a link, acts like a link, but does nothing when clicked on.

Again, I did go back into the menu options of this template to make sure this was linked as the primary menu….it is.

Not sure what else I can do???? Would appreciate any help from someone who may be familiar with this problem.

This is the site link, and below is the screenshot.

Thanks in advance
