There is only the Nutcracker layer to render with the Source, Data, Number of Channels and Channel Offset as sub-items indented and below NutCracker.
I also have another issue that I cannot left click and drag to select a range of effects for copy. I have had the capability at random times. Yesterday I opened two xLights windows to see if copy past into a new sequence would clear the problem. In one instance I was able to left click, drag and select. On the second Instance, I was not able to left click, drag and select. I can left click, drag and select in the time line to select an area to play, just not in the effects area. Single selecting groups of effects are real slow. I have had this problem on all 3 versions (49,50,51) of xLights that I have installed up to the latest version 51.
I am running on Windows 10 with the latest video drivers (updated video drivers did not fix the problem).
