There was a fix committed to beta2, but a more robust version of maintain_control_numbers will be in beta3.
It only generates a 035 if there is exactly 1 001 and 1 003 in the incoming record, so if you are creating a new record from a template, if your template does not have a 001 and a 003 in it, you should be good to go; the 001 and 003 will be filled in automatically for you once you save the record.
