Dropdown Menu - Sticking on Click

Need help to figure out why this is happening. I believe I am running 5.5.1, I was on 5.4 prior to this. Not sure that is related but, it appears something may have changed.

Expected behavior

When clicking on a menu item in a dropdown menu that once selected the menu disappears

Actual behavior

When clicking a menu item in a dropdown menu the menu remains and the content loads behind it. Until I click on the content behind which then hides the window.
