Replying to Bindings ejecting on butters?

Hey guys, so I have a little problem with my bindings. I have AR7's with Rossi Axial 2 bindings I believe. The problem is, every time I try to butter, I eject from my bindings. The DIN's go up to 10 and I have them at 8, and it's still happening. I'm 5'7 and 120 lbs. It seems like right when I get my tips and and start to like push with my feet the pop out. I have no idea what the problem is, unless they are just shitty bindings. I was thinking they might be set too far apart for my boots and I would need to tighten them a bit. Should I take them to my shop and see whats up? Thanks.
