Did you see the Item's PBS? Each Apricorn must to have a "9" instead a "0" or other number in the final. Look this:
24,GRNAPRICORN,Green Apricorn,Green Apricorns,1,200,"Green apricorn that smells like coffee.",0,0,9,
The "9" makes that the game recognize this item like an apricorn. You can see the "Icon types" it in the PBItems_Items script.
