So I have an issue as the title says. Ratchet's head doesn't pop up automatically when I lower that back hatch part. I watched video reviews and I do the same thing and Ratchet's head always pops up in the vids. Not for me. I have to use a small screw driver and insert it into the gap in his back and push down on the release switch. I can see exactly what is supposed to be happening to make his head pop out, but it's not. The grey bar piece that should be hitting the release switch isn't. Any ideas on how to fix this?
