[2022] Gear Sets with stacking buffs will not build stacks

I am a PC user.

A four piece gear setup buff does not trigger, strikers or heart breakers for example.

1) When logging in while wearing the gear set. (Repeatable)
2) When changing a single piece of the four pieces after selecting from favourites. (Repeatable)

Replication procedure:

This method can be used to replicate issue 100% of the time.

1) Have four piece of heartbreaker saved to favourite slot. Assault Rifle with Linked Laser pointer or shotgun with LLP.
2) Switch to all yellow build
3) Switch back to heartbreak saved build
4) Shoot target in the body and the linked laser point does not trigger the buff
5) Remove one piece of heart break for a yellow piece
6) Now put the removed piece back on and shoot the target. You start to build stacks.

I have seen similar issues with strikers gear set as well where the stacks will not build until you have exchanged one piece of the gear set and replaced it, which makes me think its not a LLP issue. I don't know how to recreate the issue with strikers but I found the same solution worked, remove a single piece of the gear set and the stacks start to build.
