They/them characters

I was making characters with the ai for my world and then it generated a they/them character who was a nymph when I stated nymphs have to be female in the character instructions they made it they/them I am a ally but like they need to be female I did my research nymphs must be female but the ai is dumb it wasn’t during a adventure just on the character creation screen

PS: I am a straight ally I know this post might be confusing I just stated nymphs must be girls
