Missing inventory for PC and NPC

Hello, I have a several issues with regards to the inventory. Firstly, I can’t equip my leather armor, as there is no option to equip it. Secondly, I have purchased a shortbow, but it didn’t show in my inventory, despite I have notified Franz. And lastly, I have asked Franz to add some basic inventory for NPC in my group and despite he has confirmed, that it has been done, they are missing equipment completely.
