I would send an email to Burton Customer Service (google their email), they're VERY good with situations like this. I have 2013 MalaVita's and I had a very small problems with my highbacks and they send me out 2 new ones free of charge.
They're on top of their game with customer service, they'll be able to help you out. Send them a thorough email explaining exactly what is happening, or they'll get confuzzled
Good luck brotha
