The J-4 jumper on the board is the firmware protection jumper and should not be moved unless you are updating firmware. The SLC should not be affected by that jumper position.
If the battery is good, the other known common cause of your symptom is often a failing power supply. I think if power drops off too slowly or rises too slowly, this can cause a memory corruption and the SLC will erase its user memory.
