Music Videos Not In Header Unless Type Movies

[Della Dog 19]

Is it me? With most recent Beta version of Server, unless I define the folder type as Movies or TV, the category doesn't appear in MBT. IOW, if I define the type as Music Videos, the grouping doesnt appear. If I define the type as Movies and name it "Music Videos", it appears.

 

Same with any other content type, Home Videos wont appear, unless I call it Movies and name it "Home Videos"

 

 

Thanks
