Account Applications; Applicant Gender "Unknown" now entered as blank

There was some confusion when entering an Applicant's Gender as "Unknown". After entering and saving an Account Application's Gender as "Unknown"; drilling down to the Applicant again shows the Gender as blank.

The issue is that technically Blank and "Unknown" are the same thing.

Therefore data entry has been changed, removing "Unknown" as an option and adding a blank item in the dropdown.

Note, when Accepting the Account Application and updating an existing Client, if the Applicant's Gender is blank, i.e. "Unknown", the Client's Gender is not updated. This behaviour has not changed.
