Cash Mgmt Auto Reconciliation by journal line description matching rule issue

What we would like to do, is to match a bank statements reconciliation reference value to the value found in a journal entry line description.

Below you can see the rule that I have setup, and below all of that you will see the bank transaction and the journal line showing how they would match by the reference value.

The issue is, that when using a "contains" match like I have done below, the transactions will NOT match via the semi-auto reconciliation.

Can someone please help me understand why this would not work, even though, based on the data and the logic below, it seemingly should?
