How do I report translation errors?

I’m not the greatest at spelling with Hungarian, but as I was starting the course the word for “goodbye” came up a few times. The audio recording was really quiet but after turning up the volume… He’s definitely saying “trash day” and not goodbye".

What it should be:
Goodbye = viszontlátásra

What he’s saying:
szemetes nap

It would help if you could post a link to the course!
