Website section 4.1 missing.

Finally testing out your library in practice. Looks good so far. Found an omission on your website documentation though.

Clicking section 4.1 "Additional Features" > "Callbacks" does not work, the section is missing.

Also, when you scroll to the section, it shows the title of section 4.2 labelled as 4.1.

Thanks 👍

Keep up the good work.
