OpenStudio, bad Plant Equipment Operation Schemes interpretation

edit

I have a plant loop like below in openstudio which works fine. In this stage, I use a setpoint manager scheduled with the same schedule as the outlet of the chiller at the outlet of the ice storage (just for test).

As can be seen, I'm getting three different operation schemes (cooling components, setpoint components, and uncontrolled components). According to energyplus example files and some other posts that I read about openstudio, it should be just three setpoint components at operation schemes. Since I have no control over this part of openstudio I wonder what am I doing wrong to get these shemes?
