How do you get rid of faded component designators after copying and pasting components in Altium?
You do not have to do anything to it. They do not show up in any exports and do not affect the design in any noticeable way. All it is doing is showing the expanded compiled name of the designator. To get rid of it you should be able to go to your DXP preferences --> Schematic --> Compiler and under "Compiled Names Expansion" change the dropdown next to "Designators" from "Display superscript" to "Don't display" (or whatever the actual text is -- I can't remember off the top of my head).
