Comment 17 for bug 1876460

Can't really tell. But it's obvious that you have the ability to configure your user, and also did so. We don't have the information needed to say if the configuration you did is of such a nature that gnome-control-center ought to recognize it.

So if you take a newly created user (which g-c-c does recognize) and change it in a similar way as you did with your original user, so g-c-c no longer sees it, and let us know exactly what you did, then we have something to take a stand on.
