Unbond Max differs in polkadot.staking + substarte portal when nominating

[niklasp]

When I use my account and try unbonding all my stake, polkadot staking dashboard shows a different value (than my currently active stake) after clicking the "Max" button. What is the reason for that? I would expect that I can unbond the total amount i bonded to staking.

(modal when clicking the minus in "Bonded Funds" Card) (substrate portal)

When clicking the "Unstake" button it will trigger a batch tx with "staking.chill" and "staking.unbond" where the unbond amount is my total bonded amount.

I am wondering if I am looking at a feature or a bug 🙃
