Those dampers usually rust away from center part and become loose. Try with your finger to see if it is already peeling loose. Also the rubber changes it's elasticity over time, reducing it's dampening effects.

Have you replaced the alternator freewheel clutch (if it is not freerunning in one way then you will damage belt and also crank dampener) and aux belt tensioner?

With engine running check the crank damper for excessive play and "jumping around"

There appears to be traces of big oil leak in the picture you sent or it is just dirty?
