Drop down menu won't reopen after being closed

Hey there everyone — hoping someone can help. I’m having an issue with a dropdown that I built into my navigation. In tablet/mobile view, you can open the navigation and then open the ‘Services’ dropdown, but once you hit the ‘back’ button to return to the primary menu, the ‘Service’ dropdown will not reexpand. Any ideas?

Actually, this seems to be happening to all of my hide/show interactions. Once I’ve triggered the initial interaction and then closed out of it, I can’t retrigger it — thoughts?
