Exporting model to BPMN2.0 does not include all attributes

Hi all,

I have a problem regarding exporting of a flowable model with pool and lanes into BPMN2.0. Whenever I try to export the said model using flowable-modeler, some attributes like the targetNamespace and candidateStarterGroups are set back to their default values. This is a bug?

I’m using flowable release version 6.4.3.

Thanks!
