Translation:How much is the consultation fee?
"how much does the consultation cost" was rejected but I think it's ok
That answer doesn't use the word fee (费用). A native speaker would understand it, but technically that's not what the Chinese prompt was saying.
IMHO 咨询费 is simpler and more direct, and what I would expect to hear from the person on the street.
"How much are the consultation costs?" is not accepted. Reported 6th December 2018. Rather irritating, especially since 费用 is given as costs or expenses in all other sections.
