Chiller plant supply side cooling demand rate values during simulation are largely higher than Chiller capacity

Hi All, I designed a VAV Dual Duct using water cooled chiller and gas boiler using Energyplus. Everything was done very well, but I found some weird values: in "PlantLoopDemandReportMonthly" ( "PLANT SUPPLY SIDE COOLING DEMAND RATE {Maximum}[W]" ) the Max was 51137.86 Watts and in "Component Sizing Summary", My chiller "Initial Design Size Reference Capacity [W]" is 13469.86 Watts? if I calculate the sum of Peak Cooling fro each zone from "Estimated Cooling Peak Load Components" I got 10334 watts!! same difference in Boiler and heating side?? Please could anyone guide me for these differences? Thank you in advance
