Hi Azim ,

Main reason why you get the this error is JCO destinations directly from SLD not from content administrators . remove all JCo destinations which are configured from SLD i.e remove all JCO destinations which are not configured via content administrator in this case you can see more JCO destinations in SLD than content administrator .
