Put away for LPN and Loose quantities

I have an Item which is having UOM PL-CA-EA.

And 1PL =10 CA. LPN is only activated for PL UOM in P46011.

when entered a PO for 12 CA , after the receipt system should assign LPN for one PL and remaining 2 CA should be loose items .

But, when I go to the Put away request i see 2 lines both with the UOM PL and both with LPN assigned.

I would expect loose 2 CA should not have been assigned with LPN . what is the Set up required? Any inputs will be appreciated.
