I went back the next day and discovered that the items had been stashed into a unattached "plate carrier" Pouch. Even though None of the items were placed over the plate carrier. I apologize, I thought I had checked all "containers" which were in the inventory before posting this. I also didn't know items would auto store if they were already inside the main container with free space. Also I didn't drag any of the items over the pouches, I specifically "dropped" them on items without storage while trying to re-arrange them.
