Mobile Menu showing text menu as well

My site has a problem with mobile.

The hamburger shows up fine. But it is ALSO displaying the text but the text runs off the screen and is unreadable.

I don’t think we need the text on mobile. Just the hamburger is fine.

Can you please look at my site on a mobile device to see what I mean?

How do I get the hamburger on mobile but NOT the text?

Thank you!
