iReport: Obtendo várias cópias da tabela em detalhes band

Sou novo emiReport. Então, eu quero fazer um relatório simples com base em dados.

Meu problema é que, quando minhas linhas têm menos do que o tamanho da banda de detalhes, toda a tabela é repetida em detalhes, e eu não a quero novamente. Se minhas linhas são aproximadamente 5, a mesma tabela é copiada 4 vezes na faixa de detalhes, e não apenas na tabela, mas em todas as coisas que eu coloco na faixa de detalhes. Ele se repete até os limites da faixa de detalhes chegarem.

Estou cometendo algum erro ou tenho que definir algumas propriedades da faixa de detalhes emiReport?

por favor me ajude amigos. Desde já, obrigado

Este é o resultado gerado:

Aqui está meu código de jrxml:
