What is the documentation issue?

The telemetry documentation page at https://nextjs.org/telemetry has incorrect Bulgarian translation mixed throughout the English text.

Current Behavior

• Bulgarian translations appear randomly mixed with English text
• Some sections show both English and Bulgarian versions side by side (e.g., "Will this data be shared? Ще бъдат ли споделени тези данни?")
• Footer navigation items are duplicated in Bulgarian
• This makes the page difficult to read for both English and Bulgarian speakers

Expected Behavior

The page should either:

• Display only in English (default), OR
• Have a proper language switcher, OR
• Show complete Bulgarian translation without mixed text

Examples of the issue

• "Error Feedback Обратна връзка за грешка"
• "How do I opt-out? Как да се откажа?"
• "Will this data be shared? Ще бъдат ли споделени тези данни?"

This appears to be a localization/translation configuration error affecting the entire page.

Is there any context that might help us understand?

The issue affects the entire telemetry documentation page. It seems like a language detection or localization configuration problem where Bulgarian translations are being injected into the English version of the page.

The page URL: https://nextjs.org/telemetry#error-feedback

The Bulgarian text appears in:

• Section headings
• Body paragraphs
• Navigation footer items
• All text seems to be duplicated with Bulgarian following the English

This creates a confusing user experience and may indicate a broader i18n configuration issue that could affect other documentation pages as well.
