Alguem sabe me dizer porque as linhas duplicadas?

Estou com um problema nesta query, ela retorna linhas duplicadas uma em seguida da outra Ex: linha 1 | linha 1 | linha 2 | linha 2 | linha 3| linha3 e assim por diante... Ainda não entendi porque esta acontecendo isso se não vejo o erro na query nem no while... Please me ajudem!!!

Segue codigo abaixo:
