Display error on Zandor 'Proofs of Mettle' exchanging

As the title is shown, there is a display error on Zandor 'Proofs of Mettle' exchanging

https://i.ibb.co/5kSRdDp/1.png

It is my second time on exchanging, as the image shown, I have 21,467,700 mettle and want to spent 20,000,000 mettle for 3 of 'Proofs of Mettle' .

But the window shows expend all of my mettle, 21,467,700 on the trade, but it really needs 20,000,000 so I think it is display error

Incorrect. I had 25 million mettle, after doing that, I had 5 million left over.

^Can confirm that.

Nah, it only takes the 20 million. Every time I've turned in I've had over 20 million and whatever is left over stays.

yes but no matter what amount of mettle you have it should say "expend 20,000,000 mettle", not the amount you currently have.
