When i have added the Fx chain module in pro channel, and not using it anymore
is there a way to remove it from the chain.
there's no option as i can see to " remove Module " it is greyed out !

SOLVED
( EDIT: had to collapse 1 module, because the the top bar was hidden of the FX cain module ) 

You should be able to scroll within the ProChannel to expose any modules/fx chains that don't fit into the current size.

From the image, it seems you are clicking on the top of the ProChannel itself (there is a header at the top of the PC that belongs to entire PC for on/off and preset options), not the module header. When I click on the PC header, I get the same pop-up window you have in your screen shot. I cannot replicate that pop-up by clicking on any module (or FX chain) header.

Got it solved, and thanks ;-)
