Adding More birthday years and Gender choices (again)

Hi Team,

I have gotten this question already answered way back in time....old topic 2019 , and that worked like a charm...

But I just noticed the settings I made are gone now? Are they getting deleted by an update?
And more of a problem for me is, I cant seem to find them any more?? I guess something has changed in the back-end.

I thought I found the setting (see attached image), but at saving this setting, it don't show up in the back-end?


Thanks,

Appie
