mongodb 子文档批量更新不完全的问题

有如下数据结构

{
    "_id" : ObjectId("55dc1454f754a3342000002c"),
    "title" : "出轨如旋风 防火防盗防小三",
    "games" : [ 
        {
            "id" : 1615,
            "name_zh" : "穿越时空遇见你",
            "typename" : "休闲益智"
        },
        {
            "id" : 6356,
            "name_zh" : "恋爱物语3:梦想之翼",
            "typename" : "角色扮演"
        }, 
        {
            "id" : 6505,
            "name_zh" : "恋爱物语:湛蓝的回忆",
            "typename" : "角色扮演"
        }
    ]
}

/* 2 */
{
    "_id" : ObjectId("55dc145ef754a3342000002d"),
    "title" : "炎炎夏日，跟我一起High翻天！",
    "games" : [ 
        {
            "id" : 1128,
            "name_zh" : "追击野兽",
            "typename" : "角色扮演"
        }, 
        {
            "id" : 3276,
            "name_zh" : "世界僵尸大联盟",
            "typename" : "策略游戏"
        },
        {
            "id" : 10360,
            "name_zh" : "绿色忍者蛙年",
            "typename" : "角色扮演"
        }
    ]
}

/* 3 */
{
    "_id" : ObjectId("55dc1467f754a3342000002e"),
    "title" : "简约而不简单 像素游戏合辑"，
    "games" : [ 
        {
            "id" : 1557,
            "name_zh" : "我的世界",
            "typename" : "休闲益智"
        },
        {
            "id" : 6228,
            "name_zh" : "像素地下城 汉化",
            "apk_size" : "5.39M",
            "typename" : "角色扮演"
        }, 
        {
            "id" : 6230,
            "name_zh" : "进化之地 汉化版",
            "typename" : "角色扮演"
        }
    ]
}

运行批量更新语句：
db.getCollection('xxxxx').update({'games.typename':'角色扮演'},{'$set':{'games.$.typename':'角色'}},0,1)
结果发现批量更新不完整，结果如下：

    "_id" : ObjectId("55dc1454f754a3342000002c"),
    "title" : "出轨如旋风 防火防盗防小三",

        {
            "id" : 1615,
            "name_zh" : "穿越时空遇见你",
            "typename" : "休闲益智"
        },
        {
            "id" : 6356,
            "name_zh" : "恋爱物语3:梦想之翼",
            "typename" : "角色"
        }, 
        {
            "id" : 6505,
            "name_zh" : "恋爱物语:湛蓝的回忆",
            "typename" : "角色扮演"
        }
    ]
}

}

请问更新语句要怎么写才能完整的更新所有符合条件的数据
