Submenus turn transparent second time hovered on

I just updated Maximenu CK, Params, and Mobile to the most recent versions. Now when I mouse over my main menu the first time it looks fine. But if I leave the menu, allow it to close, and then move the mouse back over it the submenu items on my first menu item have a transparent background. It was fine before the upgrade. Any ideas what might be causing it? The URL in question is:

Any help or ideas would be appreciated. I can always roll back to a backup but would prefer not to have to do so as sooner or later I am going to need to update anyway.

change

into
position:static !important;

That worked! Thank you!
