I think the UUID attribute was introduced in JasperReports 4.6.0. Therefore in order to get rid of it, you should set the compatibility mode to use JasperReports 4.5.0. This because every new version of Jaspersoft Studio or even iReport, uses the last version available of the JR library.
In Jaspersoft Studio you can set the compatibility mode at global level via "Window > Preferences > Jaspersoft Studio", then via the combo select 4.5.0 version. This will apply settings at workspace level. However you can customize this information via the project properties or even file properties. This can be really useful in common use case where you want to use the last JR version for all your reports, but you have a specific report that you want to be "JR 4.5.0" compliant.
Hope this solves your doubts and question.
Best regards, Massimo.
