Is there a way to get the category mapping to work when a supplier sends two values?

Summary:

Supplier passing two Classification domain values in punchout cart. Mapping not recognizing either.

Content (please ensure you mask any confidential information):

Supplier has other Oracle clients and this has not been an issue for them. I added both values below into my category mapping and its not recognizing either when using their punchout.

Is there something I need to do to get the category mapping to use one of them?

     <Classification domain="UNSPSC">60121524</Classification>

     <Classification domain="NIGP">62080000</Classification>
