I had this exact problem, I printed a small rectangle 3mmx4mmx8mm and stuck that to the bracket that comes in contact with the switch so it hits earlier. I tried bending it but it needed more. Now all is good. I will be replacing the switches with better quality components when I get time to help solve this.

Check the X axis left homing switch. Bend it out slightly so that when it homes it hits the homing switch .5mm sooner so that you don't scratch the left side. You should use needle nose pliers.
