Hi Jamie. Thank you for trying to address the issue. But...sorry to have to tell you this...deliberately creating a duplicate is not the right thing to do. See
https://www.wikitree.com/wiki/Help:Duplicates#Is_it_ever_acceptable_to_intentionally_create_a_duplicate.3F
which lists the only two cases, very rare, where this is permitted. Neither applies here.
Why do you say LANGESTRAET-23 cannot be edited? It has Open privacy, and is post-1700. But even so a good approach would be to communicate with the profile manager and discuss possible solutions.
