Gave a little search up in Azine, and it turned out to be a very common issue for these particular seats, due to corrosions / rusts on the gear. That's how it gets stuck, and why it doesn't move. It supposedly can be fixed by re-greasing the gear and forcing it to turn 'n click again with a use of a flat screw driver. My guess was so wrong lol. Currently, being on a hold for getting the I.M. Adapter shipped out. 1 more week or so.
