How do we remove an OPM from a flow pattern parameter?

Summary:

Hello! We created new Organization Payment Methods (OPMs). We have updated our singular Payroll Definition to these new OPMs. However, when we run the "Generate Check Payments" payroll flow pattern, we still see the old check OPM in the OPM parameter. How can we remove that old OPM from that dropdown? Where is pulling that old OPM?

Of note: we did NOT see the new check and third party OPMs until we updated the payroll definition. After we updated the payroll definition, we then saw the new Check and Third Party OPM, but we are still seeing the old check OPM. Why is it pulling old check OPM, and why do we not see the old Third Party OPM? To be clear, we do not want to see either of the old OPMs.
