i am running inventory recalculation and the resulting voucher is using Error Account, why?

Dear 

i am running inventory recalculation, and the resulting entry is using the error account in the place of "Inventory, Inventory Loss" account , why ?

i checked the item group inventory>> Inventory Loss - the account is there, i even put the Inventory, Inventory Loss in the automatic posting accounts just to make sure

and still i am getting the error account , why ?

i checked the account structure and the Inventory, Inventory Loss is within range , so no issues there
