Steps to reproduce: 1) set independent branches and create two branches FOO and BAR 2) create a patron John Doe in FOO, save him 3) login as non-super librarian into BAR 3) create a patron John Doe in BAR, try to save him 4) yellow message box "Duplicate patron record?" 5) click on "view existing record" 6) a window pops-up displaying patron data from FOO library, but this is incorrect for independent branches (it breaks GDPR rules), because only John Doe from the same library can be offered to view.
