If it is working as intended now, the display is awful.

Take my NEOX unstake for example:

I unstaked 1 (because nothing else I attempted actually did anything) and the display didn't change except for the unstaking in the right.

There is nothing in this display that tells me how much is unstakable right now, I have 496 unstaking, I have zero information to tell me how much of the 442 is unstakable, being unstaked or currently powered up for voting.
