Recent contest ranking issue

Recently I secured global rank 29 in contest CDMN21C but my ranking increased as global rank 169.
There was a question number 5 which was rejected as WA but after the contest ends it was accepted as AC which leads to increment in my rank. But its not updated in rating.
Rating was given on the basis on rank 169 i.e. +190. In my opinion my rating should increased on basis of rank 29.
