Cannot create analyzer that has more than 2 synonym_graph filters

Elastic Stack Elasticsearch
1

while trying to switch from synonym type to synonym_graph i had these settings :

  "settings": {
    "analysis": {
      "filter": {
        "synonyms_filter_ar": {
          "type": "synonym",
          "updateable": true,
          "synonyms_set": "synonyms_ar"
        },
        "synonyms_filter_fr": {
          "type": "synonym",
          "updateable": true,
          "synonyms_set": "synonyms_fr"
        },
        "synonyms_filter_en": {
          "type": "synonym",
          "updateable": true,
          "synonyms_set": "synonyms_en"
        }
      },
      "analyzer": {
        "synonyms_analyzer": {
          "filter": [
            "synonyms_filter_fr",
            "synonyms_filter_ar",
            "synonyms_filter_en"
          ],
          "tokenizer": "standard"
        }
      }
    }
  }
}

which was doing fine , however when i changed "type":"synonym" to "type":"synonym_graph"
Creating an index results in an unsable index with no apparent error message just a timeout , so then after multiple tries i decided to remove one of the filters from the analyzer and then it worked just fine , i could not find any similare error elsewhere i don't know if i'm doing somthing wrong or is it a bug ?
more info on my version of elastic :

  }, ```

Hi there @dat_boi,

Question: Did you create all of these synonyms sets via the synonyms API before making this change? Synonyms sets must exist before they can be added to indices, and if you try to reference synonyms sets that don't exist it can cause problems keeping your index in a red state. Alternately, are there any invalid synonyms in one of your synonyms sets? This can also cause problems (though the good news, is that we're actively improving this for newer versions of Elasticsearch).

If that's not the case, can you please provide any error logs that are generated when you do this?

Thank you!
