Subreport overlapping using elementGroup, pagebreak , float position

[electronic.signals2]

Hi, I've got a report (Vertical design) with 3 subreports (same file jrxml subreport) that overlap each of them.
I've used elementGroup , pagebreak and float position but I can't

Subreports span page and overlap results
Please any suggestion to avoid overlapping? Is it possible to upload jrxml and pdf files?

I'm using jasperreport 5.5.1 version.
