How to move display component of process chain

Hi guys,

I'm just wondering how to move a display component as a subordinate object of another display component? Because the display components did not follow the hierarchy I set in DEV.

DEV

PROD

I can't move them in PROD, I got the error messsage below. Is there a way to make the display component as changeable in PROD just like the other objects?

I'm not sure what option is the display component here.

Thank you.
