Output Standard Rated Net COP in OpenStudio different from Input Rated COP in EnergyPlus report - Unmet Hours

I'm setting efficiency (COP) of some DX Cooling Coil Single Speed in the AirLoop Packaged Rooftop Heat Pump equipment for compliance Baseline of ASHRAE 90.1. I'm setting the Rated COP field to the desired efficiency according to the standard. However, when opening the EnergyPlus results, in the report Equipment Summary, the Standard Rated Net COP is different, lower than what I had set the input. This only happens in the DX Cooling Coils, but does not happen in DX Heating Coils, where the outputs are the same as inputs. Could someone help me understand why this difference and how to properly adjust the inputs according to the standard.
