Setting up Sensor Offsets Copter 3.6.11

I have a copter in which i need to place front of CoG the Cube by 9.5cm and the Here2, about 4.5cm front from the Cube, while also my Z height for cube from Propellers is about 7.5cm
I was looking at INS_POS and its in meters.
I tried testing 0.095 for X, and 0.075 for Z and the according values for GPS_POS.
No matter if i typed in a dot or a comma, it would not accept such setting, but simply place 95m, 45m or 75m. Any idea why would this happen?
