Automatic Payment picking up all the payment methods in addition to method C

Hi,

Our client is facing an issue that though they have chosen Payment Method C in the parameters,however all the Payment methods are getting picked up i.e. apart from C ACH,WIRES....etc are all getting picked up and coming in the statement.This is making the statement flow into a very high number of pages and is showing as a No Payment

There are two observations here:

(1) There has been a change in the role of the Accounting Clerk since March 2012 and since then this problem has started.Could this be a reason?

(2) User is also choosing a number of Document types in parameters,could this be a reason

Kindly Help.

Thanks a lot
