Eunice here from Shopify, thanks for posting!
Sometimes, when we make changes, our browsers can store old information causing issues like this to arise. When you make a change in your Shopify admin that doesn't reflect on your storefront it's usually an indicator that your browser is keeping hold of some old information. To fix this please clear your browser's cache and cookies. If you're not sure how to do that here is a handy guide that covers all browsers.
If you're not able to view the change on your storefront after clearing your cache and cookies, please visit the Help Center and log in to your account to create a support request. While we’re not able to provide account-specific support via the Shopify Community at this time, we’d be happy to continue assisting you through live chat, email, or callback.
I hope this helps!
