user data "County"

Hello,
how can I enter the “County” in the user data section of the options menu?
It used to be possible and if one wants to insert a Sender field, the “County” variable still appears in the list, but it’s not possible to enter it in the options menu.

Is that a glitch?
Can that be altered by other means, in some config files perhaps?

I can see “Country” but not “County”. (Writer).
