Configuration Files

Required: Include a ZIP file containing Configuration.h and Configuration_adv.h.

If you've made any other modifications describe them in detail here.
Below only the modification:

// @section extruder

// This defines the number of extruders
// :[0, 1, 2, 3, 4, 5, 6, 7, 8]
#define EXTRUDERS 4

// Generally expected filament diameter (1.75, 2.85, 3.0, ...). Used for Volumetric, Filament Width Sensor, etc.
#define DEFAULT_NOMINAL_FILAMENT_DIA 1.75

// For Cyclops or any "multi-extruder" that shares a single nozzle.
#define SINGLENOZZLE

// Save and restore temperature and fan speed on tool-change.
// Set standby for the unselected tool with M104/106/109 T...
#if ENABLED(SINGLENOZZLE)
  //#define SINGLENOZZLE_STANDBY_TEMP
  //#define SINGLENOZZLE_STANDBY_FAN

/**
 * Multi-Material Unit
 * Set to one of these predefined models:
 *
 *   PRUSA_MMU1           : Průša MMU1 (The "multiplexer" version)
 *   PRUSA_MMU2           : Průša MMU2
 *   PRUSA_MMU2S          : Průša MMU2S (Requires MK3S extruder with motion sensor, EXTRUDERS = 5)
 *   EXTENDABLE_EMU_MMU2  : MMU with configurable number of filaments (ERCF, SMuFF or similar with Průša MMU2 compatible firmware)
 *   EXTENDABLE_EMU_MMU2S : MMUS with configurable number of filaments (ERCF, SMuFF or similar with Průša MMU2 compatible firmware)
 *
 * Requires NOZZLE_PARK_FEATURE to park print head in case MMU unit fails.
 * See additional options in Configuration_adv.h.

this has nothing to do with configurations

[ellensp]

Need to open issue in https://github.com/MarlinFirmware/Marlin/issues as its a marlin bug

[ellensp]

I have created a PR to fix this, but closing issue as this is not a issue with example configuration files.
