In case of Widower remarriage whose name is registered after bride name her father or dead husband?

I was a divorcee and my wife was a widower while registering marriage as per Maharashtra Regulation of Marriage Bureau and Registration of Marriage Act,1998.I had given all documents like address proof , ID proof, my decree of divorce my wife's deceased husband dead certificate etc. After getting the marriage certificate it shows her middle name in marriage certificate as followed by her father's name instead of his deceased husband name. My question is that what are the rules for registration of marriage in above case does my wife name should be reflect by her deceased husband name or her father name in marriage certificate ? For restarting her pension in the name of her deceased husband the government bodies insisting her deceased husband name in remarriage certificate as in all pension documents her name is as per her deceased husband name and the marriage registrar is rejecting the application for re correction of marriage certificate. what should i do to re correct the name in marriage certificate?
