First thing is the display language.

#define LCD_LANGUAGE en
#define DISPLAY_CHARSET_HD44780 WESTERN

Even though I have this defined in configuration.h the LCD language is more than half in Chinese.

The second issue is the bed size. I was hoping to define the build area as 235x235x250. But even though my definitions match that volume my LCD screen still says the build volume is 220x220x250.

// The size of the print bed
#define X_BED_SIZE 235
#define Y_BED_SIZE 235

// Travel limits (mm) after homing, corresponding to endstop positions.
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define X_MAX_POS X_BED_SIZE
#define Y_MAX_POS Y_BED_SIZE
#define Z_MAX_POS 250    

What am I missing?

EDIT: Language issue is solved.

2nd EDIT: Build volume issue is solved as well. turns out the defines worked but the info screen simply does not reflect the current marlin configuration.
