Issue Summary

When the browser preferred language is set to German, the Bitbucket Data Center UI displays project permissions, repository permissions, and related administration pages with a mix of German and English strings. Several UI labels, buttons, descriptions, and helper texts remain untranslated (English) while the surrounding page content is rendered in German, resulting in an inconsistent and incomplete localization experience for German-speaking customers.

This affects customer-facing administrative workflows (permissions management) where clarity in the chosen language is critical for correct configuration.

Affects

• Product: Bitbucket Data Center

• Version/s: 9.4.19 ( also checked latest 10.3 and issue still persist)

• Component/s: Bitbucket Server / Localization (German language pack — de_DE)

• Bitbucket German (Germany) Language Pack

• • Version :  9.4.0.rc5-202507022351 (9.4.19)

• • Version: 10.3.0.rc1-202605062306 (10.3.0)
• Language: German (Deutsch)

Steps to Reproduce

1. Set the browser's preferred language to German, and set the user account language to Deutsch (Deutschland) in Bitbucket DC.
2. Log in to Bitbucket Data Center as an administrator.
3. Navigate to a Project → Project settings → Permissions.
4. Navigate to a Repository → Repository settings → Permissions.
5. Observe the labels when you click on the Permission dropdown. There are 3 Administrator options, Project admin is also rendered as Administrator on these pages. (screenshots attached)

Expected Results

All UI elements on the Project permissions and Repository permissions pages (and related permission management screens) should be fully rendered in German, consistent with the bundled German language pack (de_DE).

Actual Results

The pages display a mix of German and English — some elements (page titles, primary labels) are translated to German, while others (specifically dropdown labels under permissions) remain in English. Screenshots attached for reference.

Workaround

No workaround available — customer cannot manually correct bundled language pack strings without unsupported modification of the product. Switching the UI to English provides a consistent experience but defeats the purpose of using the German language pack.
