I've read a couple reviews of these at CS's own forums and never heard anyone mention this. I can't see any reason why it would be that way either. I'd say it's a defect, though I can't be 100% sure. I'd contact the seller first. If you don't get satisfaction, then you might wanna get in touch directly with CS. CALL their customer service number on their site, rather than using email. Once you've talked to someone, you can then arrange to email pics if they want to see them. They'll probably just have you send it back in sight unseen, but you never know.
