It seems that you can only link one issue to a review in Crucible. In my case I have 5 issues part of the same change set. JIRA recognizes all of them related to the review created in Crucible (It was created from Crucible from the changeset). I'm using the validation of no unfinished reviews at certain parts of my workflows but it only works for the one issue I have linked to the review, the others can progress.
Am I wrong or is there a way to link multiple issues to the review so the validation works correctly?
