AP Parameter is set to post Product Receipt, but when posted the PO receipt, the voucher is empty.

Hi All, 

AP parameters is set to post product receipt (image 1).  Inventory Posting Profile is set up to post Purchase expenditure - uninvoiced (image 2) and Purchase accrual (image 3), but when I posted a Product Receipt, the voucher has no account.  It's empty (image 5).  Could someone please suggest if something is blocking or missing and if category pen and pencils is a problem?  Thanks so much!
