Broken Vitality support gem on Temporal Rift ? POE2

I recently unlocked the Temporal Rift spell, a Persistent Buff that reserves 0 spirit.
I have a base spirit of 30, so i added the Clarity support which reserves 10 spirit. It works great. Then i decided to add the Vitality support which reserves an additional 20 Spirit, basic math would give us a result of 30 spirit used out of 30. But when i place the Vitality support gem in my Temporal Rift slot, along with Clarity, the slot toggles off and says "Not enough Spirit". I do not have any other spirit-reserving skills, and my spirit reserve says 0/30.
Even worse, if i remove the Clarity gem, which puts Temporal Rift's total Spirit reserve to 20, it still states "Not enough Spirit", and my Spirit bar says 10/30 Spirit available, so i have 10 Spirit left for use, but even then i can't use Temporal Rift ? It appears to me as if the Vitality support gem is broken, since Temporal Rift works fine if i only slot Clarity in, but maybe i am missing a step ? I am new to the game, thanks for any clues that might help me find an answer and solve this problem.

happening to me too

the bug isnt with vitality its with temporal rift. for some reason it's requiring the spirit for passive effects but also to cast temporal rift.

can confirm the same behavior.

The vitality gem states 1% hp regen but the spell effect table in the ability menu shows 2%, and in the character menu the value correspond to the 1%, I have currently 604 hp so 6 hp/sec if it was 2% it would be 12 hp.

The behavior is the same I cannot use the spell with Vitality socketed with or without Clarity socketed but Clarity alone is fine.

I endorse. Same is happening here!
