When calling getDataset with GraphQL, if there are combinatorial parameters, the response has more rows than the number of iterations

When calling getDataset with GraphQL, if there are combinatorial parameters, the response has more rows than the number of iterations.

Steps to reproduce:

• Create a Test
• Create a Data Set with one Combinatorial Parameter and two values
  
• Use the following GraphQL operation:

  {
      getDataset(testIssueId: "186602") {
          id
          parameters {
              name
              type
              listValues
          }
          rows { 
            order 
            Values
          }
      }
  }
  

Actual Result:

• Four rows are returned
  

Expected Result:

• Only two rows should be returned, as pointed out in the Data Set management
