Just entered the following command and thought that it will add ask for 490,000

sell cvs 1 490,000

But instead I got COMMAND RESULTS:
Sold 1 units of cvs at 215000 m/unit, for a total of 215000m.

Before that the same happened with

sell cvs 2 490,000

it has been just sold to the highest bid.

Am I doing something wrong?
