## Description
The selectors printable code wasn't being used in any valid way, so that's out. Backup List printing now refers to the DiscreteOwner in the embedded selector as the ResourceOwner reference. Renamed the "Selectors"
column in the List print table to "Resource Owner" to better match what should be contained in that field.
