Change persons names ?

Hey I have the problem, that I can't change the names of people once their account is set with the E-Mail-Adress.
I even deleted them and replaced them by their real names, but the system automatically goes back to the former false name.
I also have some typos with other accounts, but can't find a possibilty to correct them.
Would be nice if you could fix that with the next update! (or tell me how it works)

Blessings from Germany!

Once a user is added, their personal information can only be changed by themselves.

This is really frustrating. Can we please control the name of the person we set up? It would be helpful for correcting mispellings and youth etc who just like to put something different in for the fun of it.
