Hey, this is expected behavior, not a bug in a specific version. Cursor is a fork of VS Code, and third-party language packs work on a best-effort basis here. Most of the editor UI gets translated, but some menu chrome elements stay in English. Right now that includes the top-level menu bar labels like File, Edit, View. Cursor’s own Settings/account page and the Agent/Chat window also stay in English. That’s why reinstalling the pack or the IDE and switching the display language doesn’t change anything. It’s not an install issue.
There’s some context and a quick how-to on the UI language in this thread: How to set the language of the software interface
Full UI localization is tracked as a separate request, see Add support for Chinese. There’s no specific ETA yet for expanding translation to the menu bar.
