Issue with mobile version of menu

Hello,

The sticky menu works great on my computer, but something doesn’t agree when it switches to the drop-down menu for smaller screens/mobile. The menu button follows me but clicking it opens the actual menu items at the top of the page rather than where my sticky menu is located. I know this is probably because of that mobile menu having a different class/div ID, but is there a way for me to add both ID’s to the sticky menu box? Also, if you could let me know which ID it falls under that would be a great help. Thanks so much!
