2014~2021 Mazda6 Sport mode issue

Mazda 6 2016, AT was replaced and initial learning was done. After that time, it is not going into sport mode. When I flick Sport mode on it just flashes 3 times and turns back off. No matter the car is cold or warm, driving or stopped.

Cruise control, ABS/TCS/DSC are not active. No codes during diagnostic and Check engine light is off.

Need to know how to fix this problem, thanks.
