k95 rgb platinum Over 20 keys with chatter

I've had my K95 for about 6 months now, it started off with 1 or 2 keys double typing, but now its most keys and makes typing easily impossible

I've checked on Switch Hitter and it's showing that 25 keys have chatter (pic attached) which seems like a lot of keys to have faults

Is there any fix for this or would it need RMA? And if so because it's been 6 months would that be with retailer or Corsair directly?

Many Thanks
