Some Push Switches don't work

I assembled DSO 062 kit (06204KP), and supplied 9V power. Then the bootloader worked fine, oscilloscope software started and everything was thought to be good. But I found that push switches labeled as "-", "LEVEL", SLOPE" and "MODE" didn't work. According to the s...
