Ok, I made a custom copy of the fixlet and added a relevance like mentioned below:-1:
(version of client >= “6.0.0.0”) AND (not (exists true whose (if true then (exists setting “__Group_0_XYZ” whose (value of it is “True”) of client) else false)))
But it went relevant to more servers as compared to servers mentioned in the XYZ group resulting in creating more servers to get exception. Should this require some modification?
