What you are experiencing with recurring tasks is expected behaviour, since it actually duplicates the task, along with the values of any custom fields.
Unfortunately it is not possible to overcome this issue by using a rule because the recurring tasks is not treated as a new task added to the project. So both triggers ‘task is moved to a section’ or ‘task is added to this project’ have no effect for this case, in order to action the status, for example, to rest back to ‘Not started’.
