Mobile drop down navigation doesn't work

Hi guys!

I just started running the foodie theme with genesis framework. For recipes on my blog, https://www.fooddaithfitness.com, I have a drown down navigation, in the primary menu area,
that also has a bunch of sub categories. I love how it looks on my computer, but not in the mobile version. In the mobile version I only have one word the says “navigation” and when you click it all the primary navigation, categories and subcategories from the drop down are al open. It makes for one very long page navigation list. How do I get the navigation menu to look like my desktop version?

Thanks!
