Mailing labels Prefix missing for Merge labels for contacts with the same address

For Individual, Addressee :

{contact.individual_prefix}

{ }

{contact.first_name}

{ }

{contact.middle_name}

{ }

{contact.last_name}

{ }

{contact.individual_suffix}

and
Mailing Label Format

{contact.addressee} {contact.street_address} {contact.supplemental_address_1} {contact.supplemental_address_2} {contact.city} {, } {contact.state_province}

{ }

{contact.postal_code} {contact.country}

Without any merging options the prefix is showing on the label. As soon as you tick address merge options, the prefixes are dropped.

Here is patch for fix.
