Reply to Problem with Pioneer CDJ 900 play button. Can anyone help ?!?!?

I purchased the CDJ's 900 from Pioneer brand new yesterday. Sometimes when a track is playing,and I press the play button to pause it, it sets some type of auto-loop in the song as if I were to hit one of the auto-loop buttons. Im really new to CDJ's but I dont believe I have pushed or pressed any other buttons that may have caused this to happen. But maybe I have, can anyone help me out and explain this happening ?

I hope my gear is broken or defective, its brand spanking new and cost me a lot of $$$$
