I recently put a new chain on my bike and I bought a KMCX 12 wax chain 12 speed specifically for Shimano. But it seems that all the links have quite a bit of slop compared to the original chain.

I have a continental kryptotal, downhill casing, in super soft compound, and whenever I press my thumb near the bead it proceeds to leak air out of it, and when I set up the tire , I made sure to seat the bead properly, I cannot figure out why it keeps leaking. The rim tape is undamaged and the sealant is not dried out.
