When a set of teams or groups has been combined in your results this means one or more of those teams/groups was below the anonymity threshold set by your organization. We combine the groups with the lowest ratings until they pass the threshold.

In the example above, neither Michael's Direct Reports, Toby's team nor Gabe's team had enough respondents in this pulse to show the results individually. Dialogue has combined all of them into one group so that Michael can see all the results that are available to him. 

This logic applies to teams and groups, such as the example below.
