Transmission ratio not preserved across reboot
My Ender 3 v2 prints were coming out a bit short on the Z axis so I performed calibration and determined I needed to increase the default Z value from 400 to 415. I made this change through the control panel here:
Control -> Motion -> Transmission ratio -> Transmission ratio Z.
However, when I restarted the printer it went back to the default value. How do I preserve configuration changes? In case it matters, I am running Ender-3 V2-Marlin-2.0.1 - V1.0.2 firmware from the Creality website.
