When creating parts with Multiple Inventory Lines you will follow the similar steps to creating your other parts, but with the ability to then set-up the different lines. Unlike our default Parts and Inventory Multiple Part Lines all do need to have a Part Number in order to be visible. Each Part Number can only exist once per location (so all locations would need to be unique).
If you are not seeing all of your parts after making this change, you would need to check that all of the parts indeed do have a Part Number.
