Dropdown Animating Repeating Multiple Times

Hey All!

It’s sporadic so not sure if you’ll be able to accurately see it, however sometimes my CSS drop-down menu is dropping more than once in succession. Other times it works perfectly and only drops the once.

Not entirely sure what the problem is (I’m having trouble tracking it) and thought I’d come ask before I tear my hair out!

Here’s the site I’m working on and you should be able to see the issue under Lookbooks. I’ve noticed it comes up more often with quickly hovering then moving away.

Thanks so much in advance!
