I didn't use any harmonizers because I specifically was wanting to use it on calus last season. I claimed the first one since we can only hold one at a time and i left the other five unclaimed. What's weird is that they're not even showing up on the pass when I go to claim previous stuff. All other 4 harmonizers are visible and i've even claimed some of them just now. One's that i've claimed are denoted by a blue check mark, but the ones at those two particular levels are simply not there, it doesn't show that there is any reward there but i know there are, especially when you compare it to the sample season pass on the website.
