I see some wear on the dark spindle, the other one looks good as do the cups. The first thing that comes to my mind is that you're loosing the adjustment you made with the adjustable cup when you tighten the lock ring. That's easy to do especially if you're using a punch and hammer to tighten the lock ring. The cup will want to turn and over tighten your adjustment. Getting an adjustment is a whole lot easier if you have the correct spanner for the lock ring because you only need one hand which leaves the other free to hold the cup in place. That would be Park Tool # HCW-5. There's also a Park Tool to hold the cup HCW-11 but channel lock pliers work fine too.
