Ender 5 plus not saving the home settings when it's turned off

I have a question i have a ender 5 plus the only up grades that have been done was the main board to a 2.2 silent board and the all meta extruder and a CR touch. when i updated the firmware. i would go to home the printer and it was fine and would home where it should but if i turn the printer off then come back and turn it one and go to home it it home in the very front of the build plate. its like it not keeping or storing the firmware setting dose anyone know what i can do to fix this ?
