Why does Vue.js/Axios don't render the data I defined?

Question

I query data from a third party API using Vue.js + Axios. The data is returned nicely however it has a bit of confusing structure (nested array).

Somehow the Vue doesn't properly work and I don't see any data renderedat the frontend.

Important to note:

The Vue adds exactly 20 html divs to the frontend after I run the code (which matchs the number of containing elements, but it doesn't display the according data(see images below)).

What might be an issue here?

Javascript part:

var app = new Vue({
    el: '#app_name',
    data: {
      info: []
    },
    mounted() {
      axios
        .get("https://cors-anywhere.herokuapp.com/https://www.api-football.com/demo/api/v2/leagueTable/" + league_id)
        .then(response => {
          this.info = response.data.api.standings[0];
          console.log(response.data.api.standings[0]);
        });
    }

HTML part:

          <div class="table" id="app_name">
            <div><p>Team</p></div>
            <div v-for="Rank in info">

            <p>{{ Rank }}</p>

            </div>

This is the JSON return, note the nested array:

{
    "api": {
        "results": 1,
        "standings": [
            [
                {
                    "rank": 1,

                        "goalsAgainst": 31
                    },
                    "home": {
                        "matchsPlayed": 18,
                        "win": 16,
                        "draw": 2,
                        "lose": 0,

                        "goalsAgainst": 10
                    },
                    "away": {

                        "draw": 2,
                        "lose": 4,
                        "goalsFor": 39,
                        "goalsAgainst": 21
                    },
                    "goalsDiff": 67,
                    "points": 85,
                    "lastUpdate": "2019-05-04"
                },
                {...}
            ]
        ]
    }
}

UPDATE

I tried it with this modification (source: https://github.com/axios/axios/issues/738) but still I don't have any data rendered

  var app = new Vue({
    el: '#app_name',
    data: {
      info: []
    },
    mounted() {
      axios.interceptors.request.use(config => {
        config.paramsSerializer = params => {
          // Qs is already included in the Axios package
          return Qs.stringify(params, {
            arrayFormat: "brackets",
            encode: false
          });
        };
        return config;
      });
      axios
        .get("https://cors-anywhere.herokuapp.com/https://www.api-football.com/demo/api/v2/leagueTable/" + league_id)
        .then(response => {
          this.info = response.data.api.standings;
          console.log(response.data.api.standings);
        });
    }

Answer 1

This is what you api gives. I think, because of a demo version.
There are no items to display. So Vue not displays anything. It's a problem with the server, not your code.
I'm worried, but maybe you need another api :(

Answer 2

 <div v-for="Rank in info">

 <p>{{ Rank }}</p>

Here Rank is an object, if you mean to use the rank key you need to

<p>{{ Rank.rank }}</p>
