Created as follows for 1 court

Haziq/Nash vs Fred/Shirley

John/Jacq vs Andre/Judy

Andre/Jacq vs Fred/Nash

John/Judy vs Haziq/Shirley

Andre/Shirley vs Fred/Judy

John/Nash vs Haziq/Jacq

Haziq/Judy vs Fred/Jacq

Noticed that Jacq does not meet Shirley in any of the games. But Jacq plays twice against Judy and Nash

Is there something wrong ? Please help !
