Bug while summon the hulkling in week 3 side quest

Hey kabam,
I don't know what is happening in side quest week 3. Node says i will get the unblockable buff when i summon the hulkling but sometime it gets unblockable buff or sometimes not. Even i tried on the opponent block. It not breaking the opponent block. I don't what is issue but in week1 it was working very fine when i played it. But now I checked week1 same issue is happening now. It was not before in week 1. I always got the unblockable buff in week 1. It is very annoying. Or just remove the button if it buggy we can play without using hulkling and kill the opponent.

Also, regarding the striker button, many people have also commented on how it doesn't work/trigger some of the time the same way the special button doesn't which leaves your champ open to being attacked by the opponent when they are just standing there doing nothing. I don't believe Kabam have acknowledged any of those reports but I could have missed it. This has been happening since they were introduced so not just this time.
They also were usable when you were being attacked last time if I recall correctly so you could rescue your champ if they were being hit with a combo but this time they do not seem to activate if you are being hit which is a change they did not bother to notify us of. If they are going to change the functioning of a feature from one time to another it would be nice to communicate that to us when it comes out again.
