Shipment Line DFF Value Not Considered in Release Rule

Summary:

We have added a Shipment Line Descriptive Flexfield (DFF) to identify each shipment line and updated it with specific values. However, when releasing it through the Release rule, this DFF value is not being considered.

Could you please advise on how to include the same shipment line DFF in the Release rule DFF field so that we can release only specific lines?
