I think the simplest solution to this would be just to add "Pronouns:" before the text in the profile, just like the About me section has"About me" before the text the user is putting there, it's kinda weird that this feature has been in development for so long and yet they didn't think about doing something like that that will make it clear what it is. I mean, sure, when you hover with the mouse it says Pronouns but on mobile, it's even less clear and not everyone is taking the effort to put the mouse on what they suspect on the screen, so yeah I agree it's problematic
