Contribution::all()does a left join onbiography, eachbiographyrow creates a duplicatecontributionrow. When a contribution has 2 biographies, the join returns 2 rows with the same contribution columns, so the GraphQL work query shows duplicates. Addingdistinct_on(contribution_id)collapses those join duplicates so each contribution appears once.
