Maiik (Mike) Duktur.
why isn't this مايك دُكتوزة؟
The letter ة is only added at the end of feminine words, e.g. the female equivalents of doctor, translator, etc. and to adjectives describing a feminine noun. Since Mike is a male doctor, دكتور in this case does not need the ة.
I also just realized you used ز ("z") instead of ر ("r"), so that's another reason it was marked wrong.
