Issue
You have two SFDC picklist fields mapped to one Marketo field but it isn't showing all picklist values for both SFDC fields.
Solution
When two SFDC picklist fields are mapped to one field in Marketo, the only values that will show in Marketo will be the values that exist in both picklists. Review the picklist values in Salesforce and add any missing values to the picklists so that they match exactly.
