removing one of order rules gives normal result

query MyQuery {
  object(where: {id: {_eq: "1"}}) {
    objectStages {
      objectStageSections(order_by: [
          {stageSection: {order: asc}}
        ]) {
        stageSection {
          name
          code
          id
        }
      }
    }
  }
