My mistake! I misread the upgrade script as I was trying to figure out where the defaults came from.
If the two phrases are used it would be nice to get those altered!
This is a very quick suggestion to add "non-binary" as a default selectable gender within user details.
Currently, the default options are "Male" or "Female" (and "No selection"). Non-binary is an accepted umbrella term for those whose identities sit outside Male/Female.
