Pull first value from a list in reports 'Assigned o: Team'

I need to pull a report that displays the first value in a list string. Ho can I update this to show only the first value. For example, this query below returns

Content Team, Default Marketing Team, Other Team.

I only want to display 'Content Team'

displayname=

linkedname=assignedTo

namekey=view.relatedcolumn

namekeyargkey.0=assignedTo

namekeyargkey.1=team

tile.name=component.teamsList

valuefield=assignedTo:teamsListString

valueformat=HTML

viewalias=assignedTo:team
