[POE2] Strange spirit using gem behavior in Demon form (infernalist)

I noticed 3 different behaviors using spirit gems in demon form:

1. Some, like skeleton archers seems to work as intended
2. Others, like fire link (dont remeber the name, the one that activates spell when you burn enemies), refuses to be turned on. I have 60 free spirit, and it requires 60 spirit but says that i do not have enough
3. Raging spirit gems activates, but does not work, spirits arent summoned.

Also it would be great if i could assign which gems are deactivated in demon form.
