I can't view the dynamic references parent and son, I also checked on the view menu and It's activated, but I can't see it, I'm using Solidworks 2017, there's a specific place where it's installed in the solidworks files, maybe in the update has been missed or in the options menu?
I believe it is a per document setting (i.e. change in your template), except when you turn it on at assembly level.
