If I'm reading this correctly, TimeTimesandhalf is expecting all the NPCs sheets to exist in the Journal from the get-go (as with prepared modules that already have maps and NPCs ready to go). As others have stated, to have ALL the creatures in MOTM in your Journal, you will need to drag them onto the table. However, you really don't need to do that for every single NPC. Instead, pull them from the Compendium when you need them.
