Rollback badge doesn't work even though you are able to edit MediaWiki:User-identity-box-group-rollback. If a user has both bureaucrat and administrator permissions, and no global permissions, both tags will be listed on the page. You can find all group tags on [ here]

If you need custom user tags or more control over how tags are displayed, you can take a look at UserTags or an easier alternative ProfileTags.
