Remove active page underline link in drop down menu?

Hi all! Wondering if there is a way to remove an active page underline effect in our drop down menu. 

I believe the issue is that the "Shop All" link is the page itself, and the additional navigation links aren't pages but categories filtered by tag, so the "Shop All" page is still considered active.

We fear it may be visually confusing. Is it possible to remove the active page underline for the drop down menu only, keeping the rest of the navigation the same? 

Here's the visual, or view the live site here. 

Thanks!
