Sublime-form in cluster jewel not working?

I got this bug in game today
My medium cluster has self-control (discipline has 30% reduced Reservation) and Sublime form (Grace has 30% reduced Reservation), but when i apply point skills then only the Self-control worked.
I have link a video about this problem, please check it.
Thank you and sorry if this is not a bug in game.
