Did I get overpaid?

So I worked 8 hours on my one and only anchor shift. Then i worked from 5:45am-11am for a training day. Both paying at $18/hour. However, Ehub is saying I worked a day I never was scheduled for. At first I thought maybe they just got the days wrong with my training. However, the day I never worked says I worked for 7.25 hours. Exceeding the amount of hours I worked on that training day. I’m not 100% sure what to do because I don’t want this to potentially come out of my next paycheck to equal things out. Any advice?
