CBECC Res 2019 Standard Desing DHW Selection

I'm modeling a SFH using point-of-use tankless electric resistance water heater. I saw that in the analysis results, the standard design is using a UEF HPWH, which makes the electric resistance water heater definitely failing the compliance. How is this standard design option selected?

I modeled the same home in CBECC 2022, which standard design adopted a point-of-use water heater.
