What are the differences between the yellow tick and let the sate blank? I have understood that putting a tick includes the state into the calculation, but I'm not sure about the way to use the yellow and the blank one. As you can see in the attached printscreen, there a slight difference if I put the yellow thick for the "lunch state" or if I leave it blank. In my case, I don't want that the lunch is include into my staff utilization. Thanks in Advance.
