Adventurers Backpack - Packs not unpacking items

I'm experiencing a problem - when I go to the Adventurer's backpack module & pull up the list of packs, then drag & drop them to the character Inventory sheet, the pack entry is added, along with it's weight, cost etc. But no items unpack at all. When I click on the details, it also doesn't list any items.
Is there anything else I need to do for this feature to work ?

FG is fully up-to-date, I have the following modules loaded - Quick-start, Players Handbook, Adventurer's backpack, Monsters & Treasure & Undying War: A0.

Another anomaly, is that when I go to 'items' on the right & hit the 'Weapons' or 'Armour' button, the window is empty, even though the weapons & armour do appear individually in the main items list.

Thanks for your time.

Hi Decade, thanks for your post. I'll prioritize some updates for these features as I work through my to-do list this Sunday.

This should be fixed on the live build. If a previous converter made a pack that is unpackable the db node will update the PC Inventory.
