In order to avoid confusion (see for example, first part of https://issues.redhat.com/browse/JBPM-9230 description) check box labels for the Notification window (screenshot attached) should be fixed, currently they are wrong:
Label for Not Started should be: (created, ready or reserved)
Label for Not completed should be: (created, ready, reserved ,in progress or suspended)

Acceptance criteria

Not started (Ready or reserved) label is replaced by Not started (Created, ready or reserved)
Not completed (In progress) label is replaced by Not completed (Created, ready, reserved, in progress or suspended)
