Short pay for WLG

So for regents week, I got to work for 6 hours online and fulfilled my 15 at my worksite. When looking at how much I would be getting paid this week, IM MISSING 6 HOURS WORTH OF PAY. On my paystub, 6 hours is not inputted and im getting 100$ less worth of pay. Is there a way to recover the 6 hours because I need that extra 100$
