Mission Planner incorrect Sonar Range units

I have a TFMini Plus connected via I2C with correct values shown in feet. However the Data Quick menu says meters. Is this a bug? How to change? Will the EKF2 use meters or feet?

EKF2 will use meters. It is a bug, I have no clue how to change it. But change the TFMini to m and it will work.

How to change it to m ?

MP shows 7 m
My ruler shows 7 ft
The Chinese manual says it’s in cm !
