mobile device hover results navigation

Greetings,

I'm using Ajax search Pro of the Ajax search lite which is highly recommended on here if you don't like the default WP search. The issue I'm having is the search results showing behind the mobile navigation instead of in front of it.

I'm using the shortcode in my primary navigation of [wd_asp id=1] and the search results display fine on desktop. But, when I switch to mobile the search results get hidden behind the mobile navigation.

See image, Search Image You can see another magnify glass in the top right, just ignore that as I haven't went into the customizer and turned that off.

Any advise would be much appreciated, I know this is probably best suited in their forum. But, I'm having one heck of a time logging in over there.

Thanks in advance.
