The reason why you are not able to see delivery item list other handling unit PK100 you did not pack anything .It is just empty handling unit.
1. PK-100
2. PK-095,
You told PK-095 contains 10 qty,means the entire qty packed in one handling unit only and the other one is just dummy handling unit.
If you want to pack PK100-5 and PK-095 then once you created the delivery.Once,then check both the handling contains any qty or not.This you can find Ttl content tab contained in Pack box in the delivery.
