Footnote strange phenomenon

[Wcowin]

This is the address I have overrides:footer.html
Before, there had been occurrences that I never paid attention to, and I couldn't figure out the cause either.

It is not guaranteed to be a 100% reproduction

Hello @Wcowin,
you did not provide a minimal reproduction, try to remove as much things as possible until you find the culprit.
Maybe even start with a mkdocs new . and try to build up a small example without your docs.

Also I don't see this issue on your deployed website 🤔 is the deployment not synced with the main branch?
