The Auto Reconciliation process is inaccurately reconciling external transactions

Summary:

Reconciliation is not accurate for external transactions when we ran the Auto Reconciliation process.

Content (please ensure you mask any confidential information):

Bank statement lines are reconciled with system transactions based solely on matching amounts. Below is the example.

Ex:

Source	Reference	Date	Amount	Type
Statement	1234567	10-08-2024	-556.65	Check
External	1239876	07-26-2024	-556.65	Check

Below are the configuration settings for matching rules.

Reconciliation Matching Rule: One to One

Rule no. 1: External Date & Type Match for ZBA

Matching Criteria: Amount, Date, & Transaction Type.

Reconciliation Matching Rule: One to One

Rule no. 2: External Reference Match

Matching Criteria: Amount, Reconciliation reference

Kindly help me to understand how it is reconciling inaccurately.
