Galactic Challenge : Stun feat looks incomplete

I have personally been in this situation, This is probably because you got close to, but not actually 30, despite what it may have looked like. Try using units like Count Dooku, Royal Guard and Old Daka as they inflict stun on basic and (or at least attempt to, after all resisted attempts still count.) If you have trouble with this, Use Thrawn to try to outspeed and get the event deathmark on your KRU. And also, If I may, what was the comp you used exactly?

No, absolutely not "probably got close". and I've talked to other people. something with SLKR stun  doesn't register somehow.

I've heard several recommendations like JMK, trench, wat etc combos. Not everyone has every character at R7, people use what they have. If we've gone thru the exhausting process of getting SLKR, we would like to use him where we can

As I have said, I have been in this position before. Also I just used SLKR, KRU, Thrawn, Palpatine and Count Dooku to complete the feat in this current challenge. Perhaps, if you are using normal Kylo Ren, You are counting uses of Sp2 as a stun when he is not at full health. And if you do use Dooku, Not all of his basics will inflict stun either.

I logged this issue to find a solution to the issue, not asking for "what else can I use ?"

I don't use OG Kylo - not relevant. I use SLKR and KRU for 12 minutes straight (after EP and 2 more die) to constantly apply stun, and it doesn't count somehow. 

The question is why SLKR's stuns are not accepted properly.
