I have a JIRA ticket with a linked Crucible review. In the "Development" panel of the JIRA ticket, the review is labeled as "OPEN":

If I then click on "1 review", the window opens, showing me more details about that review: ID, Title, Status, etc. The Status there says "CLOSED". And indeed, following the ID link to the review, in Crucible, the review is labeled "CLOSED". So why does the Development panel in JIRA say it's OPEN?
Searching for JIRA tickets with the following query also includes this ticket:
issue.property[development].openreviews > 0
Why are the development panel and this JQL query reporting a review as OPEN when it is closed?
