MARC Export 7xx $4 relator incorrectly exporting translation

In v.2.5.2, the MARC export is exporting the relator of added entries as the translation instead of the value. For example, =700 1\$aDoe, John.$4Donor is being exported instead of =700 1\$aDoe, John.$4dnr. We have confirmed this to be happening in both our local instance and the community sandbox. This creates validation errors for ILS and OCLC records.
