Challenge bugged :( [Resolved :) ]

For some reason Shaak Ti's Offense Up from her basic isn't counting towards feat completion. My theory is that the feat is only counting initial applications of Offense Up, not refreshes. So she gives you 5 the first time she attacks, then you would have to wait for characters to lose it before you get credit by a fresh application.

Unless I'm missing something? I slotted her into my Rey team and did six basic attacks, so I should have gotten 30 Offense Ups from her alone, plus a few from JTR.
