Why "Doctor Strange" is translated as "Doctor Strange" instead of "Doctor Strange"

In fact, any translation of this double meaning is possible, but one of the two meanings must be relatively more important. A sentence in the Strange movie explains it very well. After becoming a mage, others call him master. , when he heard it, he felt that Master was unhappy. He was obviously a doctor of medicine. If you call me master, wouldn't you downgrade me? So he emphasized that he was a doctor. Therefore, this doctor refers to a doctor in more contexts than a doctor.
