This has not to do with nextra, but nextjs.

Are you mapping through items to create the list?

You can try using 'use client' / useEffect to make it a client component or try giving the <li> tags distinct key values:

  <ul>
    {items.map((item, index) => (
      <li key={index}>{item}</li>
    ))}
  </ul>
