Duplicate Highlight Keys in Search Results

I'm looking at the search results, and it seems to have two different highlight keys. One called "highlight" and another called "highlights". Both seem to have the same data.

      "highlight": {
        "chats": {
          "matched_tokens": [
            "help",
            "docker"
          ],
          "snippet": "wondering if anyone could <mark>help</mark> me configure my <mark>docker</mark> hosted typesense with SSL"
        },
        "summary": {
          "matched_tokens": [
            "help"
          ],
          "snippet": " Ian asked for <mark>help</mark> with setting up SSL certificates in a Docker-hosted Typesense.  Jason provided suggestions but the issue remains unresolved due to port conflict."
        }
      },
      "highlights": [
        {
          "field": "chats",
          "matched_tokens": [
            "help",
            "docker"
          ],
          "snippet": "wondering if anyone could <mark>help</mark> me configure my <mark>docker</mark> hosted typesense with SSL"
        },
        {
          "field": "summary",
          "matched_tokens": [
            "help"
          ],
          "snippet": " Ian asked for <mark>help</mark> with setting up SSL certificates in a Docker-hosted Typesense.  Jason provided suggestions but the issue remains unresolved due to port conflict."
        }
      ],

Why is this?

highlight is the newer key which you want to use, which we had to update to once we launched the ability to index nested fields.

We’ve kept the older highlights key for backward compatibility purposes. This key won’t contain any highlights for nested objects.

We plan to deprecate the highlights key several versions from now…

I see. Makes sense.
