There appears to be an elusive bug in the references editor where, when a reference contains a template, the blue highlight surrounding the template in the reference is sometimes misplaced outside the references editor and therefore not usable. I've seen this myself a couple of times (in Chrome/Ubuntu), and it usually just stopped happening after a while and I'm not able to repro it now, so it may be some kind of timing issue. Robert Rohde also reported this today (July 8) and provided a screenshot of the bug here: https://upload.wikimedia.org/wikipedia/en/5/5f/Bad_Ref_Edit.png
