IO Proc changes in Jolting Chain?

[Coyote]

Good day... I've returned after some years off, and I didn't find any patch notes referencing a change to how IO procs work in Jolting Chain (Electric Control), but I have three IOs slotted in it that I believe worked some years ago and no longer seem to proc:
Force Feedback: +Recharge
Power Transfer: Heal Self
Performance Shifter: +Endurance

 

I also have some damage procs in it. Can someone refresh me on how IO procs work in this power now? I still see the damage procs work well, as it does way more damage than its direct power damage, but I haven't gotten any of the self-benefit procs to fire. I thought that the initial attack had a chance to trigger the self-target powers from the first target... is that not the case?

TIA

As far as I know there are no recent changes to procs. Make sure that you're looking at one of three channels: System, Combat, and Reward. Just in case the proc will so up in one of those when it activates.
