Relatório iReport não traz os campos na aba Summary

No sistema gerencial que estou trabalhando, gero em PDF um comprovante não fiscal para impressora térmica, feito no iReport, utilizando a biblioteca PHPJasperXML. Neste comprovante, quando se tem apenas um produto (uma linha) na aba Detail, os campos do Summary vem em branco. Quando se tem dois produtos ou mais (duas linhas ou mais) na aba Detail, os campos são preenchidos normalmente. No preview do programa iReport funciona perfeitamente, com um ou dois produtos.

Segue o jrxml do relatório (somente o detail e o summary):

	Os valores já vem prontos do banco de dados MySQL, nada é alterado ou incrementado dentro do Summary. Já tentei com parameter e variable mas não deu certo.

	 

	Alguém tem alguma ideia? Seria um problema no relatório ou alguma configuração de servidor?

	 

	Obrigado desde já!
