Operator names do not appear in operator list
Operator names are not visible from the Org and Security tab.
Steps to Reproduce
Bring up the operator list from DesignerStudio > Org & Security > Organization > Operators.
The Rule-Application was customized to have the Pega-Gadgets ruleset listed in it, which caused a blank version of the pzRuleOpener control to be used.
Remove the reference to the Pega-Gadgets ruleset from the Rule-Application.
