Yeah I can see last time it was commented but not fixed. Sometimes fixing broken things can cause unintended circumstances (I generally favour removing over fixing in the absence of a bug report). However, I guess pre profiles work for normal submissions just not related contact ones so it seems 'safe to fix'
