Hi,
A riddle.
We don't see your circuit, nor do you tell whether you read the datasheet, especially the section "sensitivity adjustment".
We don't know which of these schemes you use.
We don't know wheter you have read and followed these application notes:
* “mTouch® Sensing Solution Acquisition Methods Capacitive Voltage Divider” (AN1478)
* “Techniques for Robust Touch Sensing Design” (AN1334).

Added: now we see the circuit..
But: I see 12 touch pads..
Pad6: shows lengthy wiring, crossing at least 5 other sensor pads.....
