1-M and M-1 with Subset are not working properly.

Summary:

We are facing issues with a 1-to-Many (1-M) and Many-to-1 (M-1) match rule using a subset configuration. The matching behavior is inconsistent and not functioning as expected.

Content (please ensure you mask any confidential information):

We have a source system (Bank) and a sub-system (Ledger), and we've created a match rule of type 1-to-Many with Subset enabled. The rule conditions are:

• Amount: Exact match
• Date: Tolerance of -3 to +3 days

We ran the Auto Match process, but it is not working as expected. Even when the Post Date in the sub-system is only one day ahead of the source system, the records are not matching.
