Calibrate isn't supposed to trigger augments; only basic attack skills (ie stuff that doesn't cost power/fury and does damage to enemies) are supposed to be able to trigger augments. That includes defensive augments like Vanish and Void Shield.
It's very possible we've misflagged a few more for Eddies due to how they have their additional skills. If you do notice any more specific cases, do let me know as you've done here and/or post in the Bug Reports subforum, because this specific kind of bug is easy to fix when identified.
Thanks again for pointing out what you have!
