We just updated to 2018 and now I'm seeing some numbers in our assembly feature tree behind our file name " -1<1> " "-2<2>" I'm not sure what they mean, I"m guess one is the number of instances that the component was inserted, but they are all messed up and don't match anyways. But what I really want is to just remove them? Can that be done? I don't see an option the the Feature Tree Display. It can be really confusing since our file name is actually our part number. Any ideas? Thanks.
