Overexertion support not working

Good morning,

I wanted to tell you about a problem I'm encountering on Overexertion support.
The skill cannot be activated with Heavy Strike although it can be Exert.
Plus the only choice I currently have is Leap Slam while I chose in the skill tree to no longer exercise travel skills.

Have a Good day.

Sorry for this first message, after multiple tries, it's not working with the last attack with the combo Heavy Strike + Multistrike.

I'M using pestilance / viper strike and ancestral cry is not exerting either using autoextertion.
