empty form

I have a form with 10 fields which gets opened up when I click "Run" in Studio (Bonita 7.2.0). A user fills this form and submits. When I see the form in form editor, the "value" field carries values like "formInput.applicantBdmInput.firstName", "formInput.applicantBdmInput.lastName" etc.

Hi,Im working with Bonita 6.3.4
I did the "Getting started tutorial - Travel request" and when i run the process
I filled the form by helen.kelly, but when I check the manager's task list, the form for travel request review is displayed empty !

Any ideas ?
Thanks in advance for your answers.
