BLHELI_32 ESC for helicopter project seems to be not working on Mission Planner's ESC calibration

Hello everyone.

I am working on a micro helicopter project using a Kakute F7 Mini as FC and HAKRC BLHELI_32 ESC.

The problem is—the ESC calibration of Mission Planner seems to have no effect on the ESC. The motor is not working.

The FC’s accelerometer, radio, baro are all calibrated.
The ESC is already flashed with the latest BLHELI_32 from BLHELI_32 Suite.

What should I do? I might have missed some parameters or steps.
Thank you.
