Starting with Tempo Timesheets 10.19.0, CSV exports of Jira issue data now include team name instead of team ID in the Team field. This applies to data exported to CSV from Tempo's Logged Time report as well as data exported to CSV directly from Jira. In addition, TeamCustomField now returns a Team object instead of a string. Please note that you may need to update your third party apps or integrations due to this change. You can find more information here.
