Shouldn't "Jeg jobber; de betaler." be an acceptable answer as well?
Yup, report it. I would actually almost always use "jobber" about professional jobs, and maybe "arbeider" about, let's say, school work or some sorts of a project
Ok. So how do I report it?
I'm not sure how you report it now, but when you see the sentence in the course, there is a report button to the low left. Press it and you see some checkboxes. Press the right one(s), and then press done or something
