Mapping Multi Option Sets in Dynamics 365 to Multi Select Picklists in Eloqua

Our company recently upgraded to Dynamics 365 CRM. We are having issues mapping a multi option set in CRM to a multi select picklist in Eloqua. When we sync, no values are coming over. We have double checked our values and set everything to "always update," but are still experiencing no success.

Anyone else experience this issue? Any advice on how to resolve would be a lifesaver. Thank you!
