Reference Application Metadata Concepts

In the XML files, I see concepts with retired_by=1, yet retired=“false” - see below, how can a concept not be retired yet there is a record of being retired by a user?

<concept_class concept_class_id="24" name="Pharmacologic Drug Class" description="Class of medications based on pharmacologic properties as opposed to therapeutic properties" creator="1" date_created="2014-02-07 22:16:02.0" retired="false" retired_by="1" uuid="b4535251-9183-4175-959e-9ee67dc71e78"/>

Thanks for catching this. Retired by should always be null whenever retired is false.
