Description of problem:
Behaviour of 6.0.0 GA and 6.0.1 GA was that a custom task was labelled by the "displayName" parameter of such custom task.

Behaviour of 6.0.2 ER2 is that a custom task is labelled by the "name" parameter of such custom task.

I think that problem was caused by this commit:
https://github.com/droolsjbpm/jbpm-designer/commit/626d098f5988e4565a2e3384f6cb7c573dcc5cc6

where probably the return value of the "stencil.title()" expression is not same as the return value of the "ORYX.I18N.propertyNames[IdParts[1]]" expression.

Version-Release number of selected component (if applicable):
6.0.2 ER2 BPMS

Expected results:
Please, use the approach of the 6.0.0 GA or change documentation. Because the name of the "displayName" parameter describes an usage.
