our team has a problem with routing. We have prepared and approved assembly with the folder "Route parts" (automatically created during routing). There are parts (Cable, Covering, ...). In the end of the part tree is "Route1". Below is the sketch. When I edit this sketch (is not depend with or without changes) and go out from the sketch all parts in the folder are deleted except the first one "Cable".
I think we have a problem only in the methology or in the settings.
Printscreen is attached.
