When I pulled a new window I've made into our family catalogue project file I noticed that the sorting of nested types in the Family Type parameter (instance based) is wrong. See screen shot: (text is danish)

Why is Nested_Fag_b800xh1500mm : 314.215_Nested_Fag_Fast_vindue_b800xh1500mm not listed beside the other two types from the same shared family? What is the sorting based on? Looks pretty random to me.
