Fields on an RMA Record Disappear after Creating them in the Customer Center

For all the fields to be visible on RMAs viewed in the Customer Center, these fields must be set to be displayed on Print/Email in the RMA form setup since the Customer Center role (standard or custom) can only have Create permission at most on RMAs.

1. Navigate to Customization > Forms > Transaction Forms. 
 
2. Edit the preferred Return Authorization forms. Navigate to the Screen Fields tab and mark the Show checkbox for the missing fields.
