The individual element wires are broken, you used to be able to buy a conductive paint that you could repair the breaks with. I don't think that's an option nowadays because of the design, so replacement of the screen will probably be your only option.
Try getting a jet wash in there and give them a good clean, it could be bits of grime built up causing it and giving them a good blast with decent cleaner will clear them up and stop the squeaking if that is the problem.
I have been out in my 14 plate ST-2 yesterday after some heavy use of the brakes I noticed mine are squeaking a bit and I've done 3k on the clock so it's time for a clean with mine I think
I'd be a bit more gentle than using a jet washer & cleaner around the brakes, especially as it's more likely to make the problem worse by damaging seals & wires & blasting out any anti squeal grease from your pads/callipers.
Either strip the brakes down & clean them, or better still take the car back to the dealer & get them to do it under warranty.
