I’ve just re-checked the bug mentioned by @David_Henry in the 1211 thread. As far as I can see, the problem is present in 1212.
Here is a sample show file:

Have a look at the ‘Main show’ cuelist. The first cue simply gives the lights some color and intensity. The second cue has DyLOS values. When you run the cuelist, it all works fine. The colors go from Red (cue 1) to Blue (cue 2). Now Edit cue 2, and switch to the 2D View. You’ll see that the lights are Red, whereas I’d expect to see them in the Blue tones controlled by DyLOS.
