On the Miraculous Ladybug Wiki, which I'm an admin on, whenever I edit the Wiki Navigation bar, I get the error message of Level 2 being too wide. I'm not exactly sure what it means by being too wide, and I don't know how to fix it so I won't keep getting the message.

Can anyone who can look at the wiki navigation page help me figure what I need to do to shorten the Level 2 so I can edit it normally again? Thank you!
