My Capacitive Buttons Work Really Hard

Hello guys, I'm running Marshmallow on my OPO with SultanRom, today when I woke up I realized that the capacitive buttons don't work, if I try to press it tens of times or like drag my finger on it it sometimes works, It's like the touch is off in that area, I flashed the latest update for my ROM and wiped cache and dalvik but the issue still remains, what should I do?

Also it's like the calibration off or something, is there a way to re-calibrate that?
