Profile manager forms


I have created a new profile fields using profile manager, those fields have been added to the registration form, although for every field selection componenet (radio buttons/selectios) a blank option added.

For example lets say I have a sex field, my options are male and female. in the registration form something like that is displayed:


( ) [no text, just blank]
( ) Male
( ) Female

Have you encoutered that ? I have to get rid of that extra option, any suggestions how ? I would also like to set a default option, lets say male should be select by default, is that an option ?
