Can't reverse a purchasing receipt

I have an O3 with account distribution that was partially received in a couple of transactions.  The first receipt was vouchered and paid.  The second receipt was vouchered but the account distribution didn't come over so that voucher was voided.  Next we tried to reverse the purchasing receipt, however get a "reversal for non-vouchered lines only" warning, and it won't allow the reverse on lines 2, 3, & 4....only line 1.

When I look at the F0411, it looks correct as does the F43121. 

Do you have any recommendations on how to reverse this receipt?
