Cal here from Shopify, thanks for reaching out to us. That currency formatting looks correct, so it likely isn't something in your backend causing the issue. Are you using an app for the dropdown currency menu in the screenshot or is it built into your theme?
What theme are you using? Thanks!
Hi again! Have you tried to install a fresh copy of whatever theme you are using? If the issue persists, you know it's not code related. If it doesn't persist on the fresh theme, this would indicate there is still code on your primary theme that is causing this problem.
Let me know how this test goes. Thanks!
I'm sorry to hear that @CleanerCosmetic. You will need to refer back to your theme and app developers to query why the code is still causing you issues on your theme, or chat with and hire an Expert to investigate and remove any third-party code or fix any bugs in the theme.
