Private Match rules setup in the balance pool level are not appearing in the Continuous Models of the Comparison rules widget in the Model Panel. Comparison view shows only global match rules.
There are some match rule in the historical setup of intellimatch defined as a private rules as these match rules can't be re-used in any of the other reconciliations. There are some inter system reconciliations in which each system reconciliations are defined as balance pools. Each systems has their own set of different columns, probably this might be reason the match rules are defied as private rules.
