Imbalance Menu hover links not working

Hello- I recently downloaded the Imbalance theme, and used it with the Master Slider plug in. For some reason, my menu bar text will not link when you scroll over it- the link is actually slightly below the text, on the underlined area that highlights red when you scroll over it beneath it- you can see where I’m referring to if you look at the theme demo: https://imbalance.wpshower.com/?page_id=2– only for my site, the menu text is slightly above the actual links. Please help!

Thanks
