Steak really only refers to meat from a cow in English though, so they should make it more clear!
It doesn't imply that in English. If you say "I like bananas" it doesn't mean that you want to eat a whole bunch of bananas now.
The point is that it is clear that the user understands the text in Portuguese (which is clearly either singular or undetermined) and is able to translate it to English. It's not really useful to disqualify the answer so imo it should be reported.
