Cool water setpoints not followed in prototype building

I am experimenting with Energy plus and the prototype building ASHRAE9012016_Hospital_Denver.idf (distributed with E+ in ExampleFiles folder).

It seems that cool water setpoints (chillers) are not followed, see the following figure:

Also, the plant supply side temperature seems to be sometimes unstable, dropping by 5°C in one step and going back up again in the next timestep.

Is there any explanation or fix for this? Am I comparing the right variables? There are also some warnings and errors from the simulation, is the HVAC in this building set correctly?

Thank you!
