ASCII Folding not working

Elastic Stack Elasticsearch

Hi guys, I'm at the point where docuements are successfully indexing, but asciifolding does not seem to be taking effect. If you wouldn't mind, please take a look at my settings, mapping and query.

      {
        settings: {
          analysis: {
            filter: {
              min_eng: {
                type: 'stemmer',
                name: 'english',
                // name: 'minimal_english',
              },
            },
            analyzer: {
              sensible_analyzer: {
                tokenizer: 'standard',
                filter: [
                  'min_eng',
                  'asciifolding',
                  'lowercase',
                ],
              },
            },
          },
        },
      }

.. mapping:

      type: String,
      required: true,
      es_indexed: true,
      analyzer: 'sensible_analyzer',
      search_analyzer: 'sensible_analyzer',
    },
```
and finally my simple query: 

  multi_match: {
    query: this.query.q,
    fields: ['title', 'authors.name'],
    cutoff_frequency: 0.0007, // https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-common-terms-query.html#_examples_3
  },


And so.. If I query for 'andré' with this setup, I receive results containing 'André', but if I omit the 'é' and just search 'andre' or 'Andre', I get no results. 
Any ideas? Thanks a lot.
