Buddypress

Does anyone have any experience of buddypress, I am trying to make 2 profiles into one for couple with profile field, I have been struggling with this for a few hours, on the registration page it only shows the base profile fields,It is not showing extended profile fields. I am also using conditional profile fields plug in which works on the base, the others are not showing.I have deactivated all other plug ins, changed the theme to twenty sixteen, still doesn’t work, any ideas thanks
