No more Infinite Power progress?

So, I first levelled a paladin, and I’m on a priest now. I just noticed that none of the Infinite Power they earn counts towards the “Unlimited Power” achievements. It does however add to the weapon. The paladin can still earn Infinite Power, and it adds to the achievement progress.

Is that working as intended? Am I missing something?

Hi,

Im having the exact same thing.
“Main” druid adds to the next Infinite Power Achievement. Second character monk adds 0.
Achievement still says “Any character in your warband can make progress towards this achievement”

Working as intended?
