I found a difference by switching to Camunda Modeler 5: in practice when I censor an input list for any task, the modeler then shows it to me in alphabetical order, even if in reality the elements are used in the correct order in the service.
However, this does not happen in the old Modeler. Obviously, all of this involves a nuisance in the design with the new Modeler.
Sorry for responding that late!
The alphabetical order for lists in the properties panel was introduced via Camunda Desktop Modeler 5.0.0. If you think that does not make sense for some properties, feel free to file an issue in the project repository
