Dynamics _label functionality for OptionSet yielding blank items

[dean1]

There is an option set "Scorecard Question" which exists off the entity "Score Card". I have a gallery 'Score Cards' where I wish to show a list of 'Scorecard Question Label', but blank items are showing up and I cannot find such blank entries in Dynamics CRM.

Does anyone have suggestions for use of this undocumented "Label" / "_label" functionality? 

Repro steps:

1. Create a Gallery with a Dynamics CRM Entity 

2. Identify an Option Set within the Opportunity.

3. Add a Label with Text = 'Scorecard Question Label'. Note: I've also tried using the '_scorecardquestion_label' syntax and the same results are yielded.
