Unwanted show_doc Documentation Automatically Added 3x to Rendered HTML

[nicomarr]

Description

When using nbdev to write a Python package, I've encountered an issue possibly associated with the nbdev_export command:

• Running nbdev_preview to check the rendered HTML version of my source code for documentation results in the documentation for show_doc being automatically added three times to the very end of the rendered HTML page. The same is true for the published page with source code on GitHub pages
• This occurs even though the built-in nbdev show_doc function has not been imported or used in the Jupyter notebook containing my source code (named 01_code.ipynb, following the nbdev documentation).
• The markdown for show_doc appears in the local markdown file _proc/_docs/core.html.md located in my project's root directory and in the published page on GitHub pages:

Current Behavior

The show_doc documentation is automatically added three times to the end of the rendered HTML and markdown files.

Expected Behavior

The rendered HTML and markdown files should only contain documentation for the code actually present in the source notebook.

Attempted Solutions

• Ran nbdev_clean (no effect on this issue).
• Re-ran nbdev_export (doesn't fix the issue).
• All tests run successfully with nbdev_test.
• Ensured no mixing of import statements with actual code (known to cause issues with nbdev).

Any suggestions to fix this would be greatly appreciated. Thank you!
