I am trying to add a Related List - Single component to a lightning record page for the WorkOrder object.  The related list I am trying to display is for Service Appointments.  This works completely fine with one record type we have for the WorkOrder object, but when I look at Work Orders for other record types, the component does not display.  I have verified that the other Work Orders I am looking at do have service appointments linked to them.  We only have one lightning record page for the Work Order object and it is the org default.  I can't figure out why it is visible for one record type and not the others.  I looked at the help documentation and the suggested fix is not the issue.  Help!
