I don't know if it's possible but is there any way to add an indication of the subject in the hint? I have a feeling the hints are auto generated but it would be handy here I think
πορτοκαλάδα is not orange juice but orangeade. Orange juice is χυμός πορτοκαλιού/πορτοκάλι.
Why drink orengeade is translated as Γιατί να πιεις πορτοκαλάδα; as it has the meaning of "why do that", and it shows a question about what you are about to do and not what you are doing.
