Logstash escaping characters, want to disable

One thought I had was that there might be different types of the field, which is was ("path" was just a text without any analyzer or anything).
But I recreated the index and reindexed the documents with the same settings as the index created by FSCrawler has, but it's still encoded every " as \" and every \ as \\

        "path": {
          "type": "keyword",
          "fields": {
            "fulltext": {
              "type": "text"
            },
            "tree": {
              "type": "text",
              "analyzer": "fscrawler_path",
              "fielddata": true
            }
          }
        },


            "virtual": {
              "type": "keyword",
              "fields": {
                "fulltext": {
                  "type": "text"
                },
                "tree": {
                  "type": "text",
                  "analyzer": "fscrawler_path",
                  "fielddata": true
                }
              }
            }

*virtual is from FSCrawler and "path" is from Logstash/JDBC/SQL Server
