Why isn't the Create Primary Work Relationship field visible for a global transfer even though it's set to Visible in the Transaction Design Studio?

When you set the Create Primary Work Relationship field in the Local and Global Transfer flow to Visible, this is what happens:

• The field is visible when you create a global temporary assignment by selecting the transfer type as Temporary in the Local and Global Transfer flow.

• The field isn't visible when you do a global transfer by selecting the transfer type as Permanent in the Local and Global Transfer flow. This is because the work relationship is set to Primary by default in a global transfer. There's no choice of whether to create a primary work relationship or not.
