I have a part with 4 instances that show up in an assembly folder marked "Top Rails and Hardware". They should not show up there because when you scroll down, these same instances are actually part of "DerivedLPattern1".
How can 4 instances, which are clearly part of a derived pattern, show up in a folder that I created? They're the same instances. If I hide the parts in the folder, the same instances become hidden in the derived pattern, and vice-versa.
Has anybody ever seen something like this before?
