Side Hustles

What exactly counts as a side hustle? I have a teen who needs to reach level 3 in one to fulfill the goal-oriented aspiration thing, and from the way it reads I thought ANY part time job would work, but apparently not because she's at level 2 of barista and it's not registering. So does it have to be one of the two new jobs that came with the pack? Or is the whole thing just not working right? It definitely says, "To join a side hustle, use a phone or computer and select Find a Job." So it seems like any job should work.
