Need help with SalesForce Sync

Hello,

I’m using the Salesforce Sync Provider and running into an issue with Person Accounts. Because they don’t have the Account Name field, but instead have Last Name as a requirement, when these records sync to Acumatica, they fail to sync any changes back up to Salesforce because this error. 

Has anyone who has used the Salesforce Sync had/solved this problem? I was thinking setting up some If’s in the export scenario with a boolean would work but I did not have any luck with that.
