Digital Servos

So our team just got a small batch of digital Hitec servos (HS-5485HB) and are having an interesting problem. When we code them we can set them between 0 and .9 fine, the problem comes when we send it 1. When set to 1 it just continually spins never stopping, it even keeps spinning after we disable the bot. I was curious if any one else has had this problem and knows whats causing it / how to fix it.
