EMR Zeppelin removes DepInterpreter

Question

I am running zeppelin 0.7.0 on an emr-5.4.0 cluster. I am starting a cluster with default settings. The interpreter is %spark.depnot configured by EMR.

I edited the file /etc/zeppelin/conf/interpreter.jsonas follows:

"2ANGGHHMQ": {
  "id": "2ANGGHHMQ",
  "name": "spark",
  "group": "spark",
  "properties": {
    "spark.yarn.jar": "",
    "zeppelin.spark.printREPLOutput": "true",
    "master": "yarn-client",
    "zeppelin.spark.maxResult": "1000",
    "spark.app.name": "Zeppelin",
    "zeppelin.spark.useHiveContext": "true",
    "args": "",
    "spark.home": "/usr/lib/spark",
    "zeppelin.spark.concurrentSQL": "false",
    "zeppelin.spark.importImplicit": "true",
    "zeppelin.pyspark.python": "python",
    "zeppelin.dep.localrepo":"/usr/lib/zeppelin/local-repo"
  },
  "interpreterGroup": [
    {
      "class": "org.apache.zeppelin.spark.SparkInterpreter",
      "name": "spark"
    },
    {
      "class": "org.apache.zeppelin.spark.PySparkInterpreter",
      "name": "pyspark"
    },
    {
      "class": "org.apache.zeppelin.spark.SparkSqlInterpreter",
      "name": "sql"
    }
  ],
  "option": {
    "remote": true,
    "port": -1,
    "perNoteSession": false,
    "perNoteProcess": false,
    "isExistingProcess": false
  }
}

I need to manually add the following and restart zeppelin:

{
  "class":"org.apache.zeppelin.spark.DepInterpreter",
  "name": "dep"
}

Is there a way to force EMR to use zeppelin's default settings (and not delete this configuration)?

UPDATE

Can someone explain why the cluster that I just created this morning by cloning the original cluster has a completely different configuration?

"interpreterGroup": [
    {
      "name": "spark",
      "class": "org.apache.zeppelin.spark.SparkInterpreter",
      "defaultInterpreter": false,
      "editor": {
        "language": "scala",
        "editOnDblClick": false
      }
    },
    {
      "name": "pyspark",
      "class": "org.apache.zeppelin.spark.PySparkInterpreter",
      "defaultInterpreter": false,
      "editor": {
        "language": "python",
        "editOnDblClick": false
      }
    },
    {
      "name": "sql",
      "class": "org.apache.zeppelin.spark.SparkSqlInterpreter",
      "defaultInterpreter": false,
      "editor": {
        "language": "sql",
        "editOnDblClick": false
      }
    }
  ]
