Sounds like you used the vendor field when it was created so that entry created two. The charge in AP and the payment at the same time. If you back up one record it should be the charge (unless it was edited after the fact). 
but that also means it will be listed in the vendors paid AP in 4-4

That's it!  Thank you!!  I had no idea. 

No problem.  So I tell clients if you need the vendor history then using the vendor field in cc charges is fine, just remember that if you have to fix the amount, you have to void the vendor payment which open the invoice back up.  Edit the invoice and then repay it with the credit card thru AP payments.

But don't add vendors for random purchases or gas stations etc.  Just use the payee field.  Then it only creates one record that debits the expense and credits the cc liability.
