I have a location setup to require a pick

I have been testing with an item requiring a serial numbers, an item requiring a lot numbers and an one that requires both.
When I create an inventory pick for the lot only item, the lot number prints on the picking list
However, when I create an inventory for the serial number only, the serial number does not print
If I do the one with both, neither the serial or lot number prints.
I do that the Show serial/lot set to Yes
What am I missing?
