If applicable, add screenshots to help explain your problem.

**Additional context**
The fix is in the bcgov-arches-common repo, which fixes the JS and has a migration to fix the card_x_node_x_widget data (defaultValue is null, not false). Additional migration needs to be run in bcfms to fix the existing data in BCFMS.
related issue is here: bcgov/bcgov-arches-common#154

Start in the bcgov-arches-common JavaScript for checkbox-boolean-widget and its migration for card_x_node_x_widget, comparing defaultValue handling for null and false. Then inspect the BCFMS migration needed for existing data and verify the reproduction flow no longer removes the contributor from the dropdown.
