Unable to add Run Ruleset to Classification SD Workflow

Hello everyone, has anyone run across and repaired something like this?  I'm trying to add a Run Ruleset component to the SD.IncidentManagementSimple.Classification project, so that when the evaluations determine that the owner has been changed and saved, the corresponding ruleset runs.

What seems like a fine idea is quickly quashed with this error message:

Any ideas on this one?

Thanks!!
