Menu Error After Installing Law & Justice Theme

I’ve encountered a glitch with the menu bar and nobody can seem to figure it out with the Law & Justice theme. The site in question is https://www.chriskarpan.com

If I use any page as the main menu header, (ex. ‘Your Rights’) and then place subheadings under it (ex. Cash Bail/Bail Bonds) you cannot click on the ‘Your Rights’ tab without it completely disappearing. It also will not navigate to any destination. I’ve tried creating a new menu and made sure the destinations are correct, but I’m still having this problem. Advice?

Completely unrelated, but I also can’t make ANY changes to the copy without it completely going haywire and turning into a bunch of jibberish. Maybe this is caused by the same thing. Or the editor? Anyway, thanks in advance for your help!
