XtraReport always promt for entering parameter (Visible = false)

I am using Devxpress 12.2.7, in ver 14, if I set the parameter visible = false then they will not be asked for entering. Now, in version 12.2.7, I set visible = false, passed value to them, but the parameter still be ask to enter.

This is the startup state of Printcontrol, the values is passed before, not by typing
