I think my issue here as you can in attached file there are additional subassemblies(fake) beside my original one and let me tell other station had a link code and everything was ok because there weren't any additional subassemblies.
May if you haven't any idea i will post my DWG.
I figure out an issue and let me explain what happened.
Additional subassemblies(fake) appeared at hairpin location only
As you can see in attached file i have a hairpin in my project
