Parameter missing after replacing fixture

When I program a show with a fixture with lets say, only RGB colour parameters and then I replace that fixture with a fixture that has also a CCT channel, that CCT parameter is not showing up on screen and also not recording in color palettes (even when using Make Absolute). I have to manually add that Parameter, using the Parameters key (which is not there on a program wing, so that was a bit of a search!).
