Horizontal Main Report causes Error : Subreport overflow

I asked multiple question in this website and in stackoverflow, that improved both my knowledge with Jasper and the quality of my reports.

And now, I have a report, that you can find in the answer in the link below:

https://stackoverflow.com/questions/57057135/jasper-print-when-create-white-space/57057795#57057795

It works great, just one last problem:

The order is vertical. What we can see is Argentina, Brazil, Austria, Canada, etc.. But I want Argentina, Austria, Belgium, Brazil, etc...

If I change the print order I get the error : "Subreport overflowed on a band that does not support overflow". How can I solve it? Any ideas?

Thanks
