Marlin calls load function when validate EEPROM contents, currently the load routine overwrites runout enable parameter in a validation process:

Thanks, that is where i "fixed" it as it was annoying as i have an audible warning along with a blinking red icon background when the sensor gets triggered. I guess when validating the eeprom it shouldn't do this?

If you disable the filament run-out sensor and save settings, it will kept disabled after validating.
