Hi guys, I'm designing a pcb which should have 4 (later 8) exactly the same units on it, together with some other stuff. To accomplish this I was thinking about using modules and this is what I did: First I created a whole new project for it ([https://easyeda\.com/mijnmodelbaan/lightning\_02\_copy](https://easyeda.com/mijnmodelbaan/lightning_02_copy)) Then I created a schematic and a pcb from that schematic. Routed a few tracks by hand, used the local autorouter for the majority of the tracks and after routing the last tracks by hand, I was finished. Well, that is to say, after routing the last few tracks by hand and correcting the DRC errors it was finished. Then I saved the schematic as a schematic module and the pcb as a pcb module and started a new project ([https://easyeda.com/mijnmodelbaan/module_testing](https://easyeda.com/mijnmodelbaan/module_testing)). In this project I created 2 sheets and on both sheets I put the schematic modules I created earlier. For the first one I used the letters 'QQ', for the second one I used 'AA'. After doing this I noticed the components were all renamed with the chosen letters (QQ, AA) in front of the original names.  But of the Nets only a few were renamed, 16 of the 49, and the ones not renamed pointed to both sheets.    This is not what I expected. I created an empty pcb (just to see what would happen) and put 2 pcb modules on it (the ones I created earlier). Here the same problem arised: after importing the changes only 16 of the 49 Nets were ok.  Please let me know what I did wrong so I can solve this, preferably in a simple way. Thanks for your time.
