Remove Prefix from Addressee
You might try the display_name short code (assuming it exists as I do not use WP mysqlf)? You can control the way the display name is built in Administer>Customize Data and Screens>Display Preferences.

Alternatively you can set customized addressees for your contacts? That is a lot of work if you have to do it manually but you could also create a scheduleld job to do this with the API if you have any development skills available?

If you want to make sure the prefix is not in the display name you change the settings for display name. Standard they will probably be:

{contact.individual_prefix}{ }{contact.first_name}{ }{contact.last_name}{ }{contact.individual_suffix}


Change into

{contact.first_name}{ }{contact.last_name}{ }{contact.individual_suffix}
