Our deposit schema allowed multiple FundRef programs (<fr:program>) within CrossMark deposits. This was an oversight, only one <fr:program> should be deposited. The <fr:program> element can contain multiple groups of funder information within a "fundgroup" assertion as described in the FundRef documentation.
Our deposit schema is being updated to enforce this. If you have been depositing FundRef data with multiple programs, please redeposit as this affects how CrossMark displays your funding information.
