Apollo pex cincher jams

I have a brand new cincher, the same one in the link. I've only used it a few dozen times, and I really like it, however it occasionally jams and won't release off the ring after it is fully cinched. It is not a matter of overtightening, I usually have more play to continue to tighten if I wish. It's not a huge deal, just annoying. I can work it out with any combination of jiggling, force, or continuing to crimp, but no one solution seems to work consistently. Any ideas of what may be happening and how to prevent or fix it?
