DDJ RR PROBLEMS

Hey please i need help with these issues on my DDJ-RR:
• Mic is always turned off on rekordbox (can't use MIC FX, MIC EQ and MIC TALK OVER) but i can still hear my voice from the mic in the speakers
• Pads on the left side; while pressing any of the pads from 1 to 4,
the pad under the one pressed is automaticaly activated (right deck is fine)

I have tried to restart my pc (windows), restart the hardware and the software, replacing the cable, updating to the newest version, trying another usb port and nothing worked
