If you add a joint individual Profile in FIMS, where the woman is on the Profile 1 tab and the man on the Profile 2 tab, everything is built correctly regarding Report Name, Mailing Label Name and Salutations (e.g. Mr. and Mrs. Robert Smith).
With CRM, if you add a joint individual Profile with this same scenario, you need to indicate the gender (female, male) for each person for the Salutations and Mailing Label Name to be built correctly. If gender is not added, the prefixes will be built backwards.
If the Profile has already synced to FIMS, to fix it, go to FIMS to the Salutation tab and click the Build Salutations button. Once that Profile syncs back to CRM, the name fields will be corrected.
