Product Prices Randomly Changing

Product prices displaying on front end just randomly changed and are incorrect. When I attempt to edit the product, the correct price is showing in the back end, I update and save it and incorrect price still shows on front end. I’ve attempted to re-input the price, unpublish and republish the product……nothing is correcting the pricing. Just checked the WC version running on the website and it says 3.0.8. Why is that version not showing as an option in the drop down menu???? I updated the WC this afternoon with the latest version. Is 3.0.8 the latest version????
