Wrong default Language in my Shopify Store

When I opened Shopify Store, my IP was in Vietnam. Then I changed default language into English, Time zone, Location, Prefered language in Account setting, ect. But my menu now was mixed between English and Vietnamese. Some of these parts in my theme are Vietnamese. So how can I fix this? How to change all into English.

To resolve the issue of mixed language content in your Shopify store, follow these steps to ensure that all parts of your theme are consistently set to English:

  1. Check and Update Store Language Settings:

    • Shopify Admin Panel: Go to Settings > General and ensure that your Store Language is set to English.
    • Account Settings: Double-check that your account settings reflect the preferred language as English.
  2. Theme Language Settings:

    • Edit Theme Language: Go to Online Store > Themes. Click on Actions next to your active theme, then select Edit Languages.
      • In the Edit Languages section, ensure that all fields are set to English. This includes tabs like General, Products, Cart, Checkout & System, etc.
      • If you find any fields still in Vietnamese, manually translate them to English.

How can I change from English to Vietnamese? Because there is no Vietnamese option in my account’s Preferred language.
