Sota Reflex Clamp Loses Contact with Record

I've got a reflex clamp that I use on my Star Sapphire. I've notices a couple of times that if I simply lay the clamp on the record and push the lever down that the action of the clamping pushes the clamp up, leaving a gap between it and the record. I imagine that doesn't make the clamp very effective. If I apply a little pressure when I'm locking it down then it stays where it's supposed to, but this leaves me concerned about stressing the suspension.

Anyone else experience this and have any thoughts?
