Hi Rose,
If you change the currency to any of the other ones except US dollar, then I think you’ll be able to see some products having this sale badge on them even though they’re not on sale (for some reason the wrong sale badges are not shown when currency is set to USD). Do you think it might be some problem with the currency switcher plugin? If it is, our website needs the currency switcher plugin, so is there a way to resolve this without having to disable the plugin?
Thanks,
Sophie
