group name is not showing when I do $id but group id exists under /etc/group

I created a new user zzzz and its primary group ID was 9472 so I went to $sudo vi /etc/group and changed the group ID to 9471(which was the group id of already existing one user avaya) and then I deleted the user and group both .
after that now its not showing any group names.
if you see the below info the group name is showing only ID and not name .
but all these names with group ID exists in /etc/group and /etc/passwd
