I am using Marlin firmware with a ramps board on an Anet A8 printer.

The bed size for the printer is 220x220 and that is stated in the configuration.h file. When using mesh bed leveling, the nozzle jumps to the first corner on the bed perfectly after setting the x-min to 5.0 but the next two points are off the end of the bed. Here are my settings:

// Travel limits after homing (units are in mm) #define X_MIN_POS 5.0 #define Y_MIN_POS 0.0 #define Z_MIN_POS 0 #define X_MAX_POS 220 #define Y_MAX_POS 220 #define Z_MAX_POS 240 

What could be my issue?

The problem is in the code. Please use these:

// The size of the print bed #define X_BED_SIZE 220 #define Y_BED_SIZE 220 // Travel limits (mm) after homing, corresponding to endstop positions. #define X_MIN_POS 5 #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 240 

Your problem will be ok.
