Navigation – Dropdown not working

Hi all

i’ve a little problem on our page (www.mannschaftsheim.net) with the navigation, the subnavi under “Team” there are 3 Sublinks (Members, Games, Matches).

When i “shrink” the Page (Mobile View) the Subnavigation Works but not in the Fullview.

I hope some of you could find a clou why this doesnt work anymore :/ Thanks in advance 🙂

Friendly Greetings
