[Forum] Forums Now Display Differently

[Futhark]

Today I've added a new forum Category with 3 Forums in it. They are different to the rest of my forums, they have a little icon like a family tree beside the name. Have I done something wrong?

you forgot to choose 'Yes' or 'No' to the 'Act as forum' option in the forum manager :
'No' for the category
'Yes' for the forums in the category.
