Energy Plus LoadProfile:Plant from Schedule:File issues

I am creating load profiles for a plant model using an 8760 csv file. The load profiles are the only objects on the demand side of the HHW and CHW loops. When I run the model, the loop demand rates do not match the load profile objects I specified. I have exported the Schedule:FIle object, and that seems to be importing ok, although there are no units associated with it. Does it need units? I didn't think so because as the load schedule it should automatically assume it is [W].

I am using a CentralHeatPumpSystem Object and have noticed when the flow-rates through the ChillerHeater:EIR are changed, the loop demands change (#weird).

Using EnergyPlus 9.0.1

It's hard to tell what's going on without getting more information. Ideally the CSV file + the IDF model would make it easier to troubleshoot, but if you don't want to share this, could you at least give us the snippet of your LoadProfile:Plant object (which is defined by the load profile schedule, but also peak flow rate and flow rate schedule) and a table comparing what your inputs and outputs?

@JulienMarrec I have placed the IDF and CSV in the link below. I had this model running with a smaller load. As soon as I increase chiller capacity, flow rates, and load profiles, it crashes. I flattened the chiller curves so they should operate at a constant COP throughout the year.
