Update on Sales Order header AUTO BATCH SELECTION is not transferring to the lines

Dear 

I am creating a sales order and my initial setup is Reservation MANUAL , so when it is time to deliver the warehouse manager goes to the Sales Order Header and changes the reservation from MANUAL to AUTOMATIC and checks the below checkbox AUTOMATIC BATCH SELECTION 

so then he clicks on the LINES tab to switch from the HEADER to the LINES view , the system prompts him UPDATE RESERVATION , he checks YES and goes to the lines

now at the lines, my items are switching from MANUAL to AUTOMATIC reservation , but the AUTO BATCH SELECTION is not updated i still have to check them myself manually.

is there are parameter somewhere i should check for the Lines to become updated as the header?
