Autoreconciliation by providing only bank account parameter it generates data corruption

Hi
Autoreconciliation by providing only bank account parameter it generate data corruption


Customer case:

First file :

* I´ve unreconcilied manually (By the Bank statement form) one misc receipt line
* I´ve ran the Autoreconciliation program with statement number parameter
* Result ok

Second file :

* I´ve unreconcilied manually (By the Bank statement form) one misc receipt line, from the previous statement
* I´ve ran the Autoreconciliation program with account parameter (without number statement or dates)
* Result not ok

You have the trace files attached

Please advise if there is a minimum grouping parameters which should be used when running Autoreconciliation on receipts?
