My Employer Removed My Work Overtime Hours.

I’ve worked at a local restaurant for about 4 years now. I’m an hourly wage employee and quickly was one of the hardest working and most working employees. All that to say, I used to get tons of overtime (1.5x) pay. Well a while back I noticed that I clocked out, my last day of the week with 44 hours and the next day on our work app, I noticed my out time from my previous shift was edited 4 hours and now the system had me at 39.98 hours. And I noticed my time punch in the app was moved to call it 7:30 when I left at 11:30 (these aren’t the specific numbers but just an example) the schedule I was working would get me 2-4 some times 6 hours of overtime but no matter what for a good while I noticed that any small amount of over time would always be edited to 39.someodd hours. I do not know if it’s the GM of the store or possibly the corporate owner that lives states away but does have a particular interest in this restaurant. What do I do, it doesn’t seem like this is some magical “I’m about to get PAID” scenario but I could be wrong. I haven’t worked overtime hours in a while. Since I wasn’t getting paid for it I started refusing to come in. I have pictures of my paper clock out slips and screen shots of my edited times the next day, but it’s only a couple of examples of more minor changes (2/3 hours) I have no idea how long they have been doing this, if it’s just me they’re doing it to. What can be done? Can I sink this restaurant and get a bag? Or is it best for me to look for another job and avoid the legal mess? (Already looking for another job as I can’t stand the restaurant repetitiveness anymore) I live in Arkansas if that helps. Thanks
