Approved use case to default Bargaining Unit based on DFF is not working

Summary: We have approved use case #39 where we want to Default the Seeded Bargaining Unit field on Position based on a DFF ATTRIBUTE4 under Context Segment on Positions. So it should autopopulate the DFF value to Seeded Bargaining Unit field.

But after setting up the rule on Field Modification it's not defaulting the Bargaining Unit value.
