Reconciliation Issue

Using qkn 05p r3; received credit card bill that does not have online access. There are 3 transactions adding up to 68.59 & a credit from last month of 41.40. When the 3 transactions & payment are cleared-- I end up showing cleared balance of 88.59 thus a $20 discrepancy. I do not get the error message that the last reconciliation was in error. The last transaction from the prior billing was for $20 & there were no issues w/that reconciliation. However, when I tried to re-reconcile the last bill qkn now shows a cleared balance of $61.40 instead of $41.40. In the past I have had reconciliation errors w/bank statements but always received error message & was able to fix by deleting prior reconciliation & starting over; I don't have that option with this error. Any suggestions will be appreciated. dj
