Sync- CRM to Desk not pulling properly

Sync- CRM to Desk not pulling properly

Hello, 
I'm having an issue trying to get a certain sync to happen between CRM and Desk

- CRM> Contacts> this area displays the First Name, Last Name, and Contact name.  The Last Name is pulling in the full customer name and I have already updated the Layout to make the first name mandatory. 
- My end goal is to get the customers full name (preferably pulling from the First and Last name fields) and have it be transferred over to the Desk>Customer list. 

- I've chatted with Support and am not able to get too many answers
- I'm not sure if my acct needs to be an Enterprise account to get more fields in the sync configuration screen. 

Any help from the Community is appreciated!
