Unleash Chaos Spend-Field is bugged or idk how to use it

In the demiplane character sheet it is impossible to use the buttons for the “Spend” field thats part of the ability. I can adjust how many Tokens are on the card, I can make the spellcast roll, and when my tokens aren’t full I can mark a stress. Regardless of what I do, wether the tokens are full or not, wether I make a spellcast roll beforehand or not, I cannot use the “Spend” field as the “+” and “-” button are permanently disabled. My expectation was, that a button pops up with a preconfigured roll of d10s equal to the amount of tokens spent but I now have to configure it manually. During the session one of the players took this to mean that the ability is disabled and didn’t use it.
