Hi guys,
When a Story gets created with a custom date (for example, we call it "Delivery Date"), its child (Subtask) need to have Due Date which is Delivery Date minus 25 days.
For example, when a Story gets created with Delivery Date (12/31/23), then its subtask should have Due Date (12/6/23).

But when the subtask gets automatically created, its due date does not show at all.
Am I getting a wrong formula for that?
How can I get the due date which is supposed to be Delivery Date - 25 days?
