服务端API保存表单数据，数据返回异常、界面展示异常

我是按照官方文档：https://open.dingtalk.com/document/orgapp-server/formdata-structure-description-for-returned-form-instances 进行服务端开发，以下是我传给宜搭的数据格式

{

    "radioField_lam9q83x_id": "disabled",
    "selectField_la0oze4t_id": "1",
    "selectField_l9qf3byy_id": "0",
    "radioField_lam9q83v_id": "disabled",
    "textField_l75lkp2s": "OD",
    "selectField_lb4n39p4": "无",
    "radioField_lam9q83z_id": "disabled",
    "selectField_l74ppv37_id": "1",
    "selectField_l9w6viia_id": "件",
    "selectField_l74ppv35_id": "M",
    "cascadeSelectField_l773a9oz": [
        "连衣裙",
        "梭织连衣裙"
    ],
    "selectField_l74ppv37": "第一波",
    "selectField_l74ppv35": "夏",
    "radioField_lam9q83t_id": "disabled",
    "selectField_l75lkp2o": "吴沛衍",
    "textField_l74ppv39": "连衣裙",
    "radioField_lam9q83y_id": "disabled",
    "textField_l74ppv38": "OD23ML7046",
    "selectField_l9w6viia": "件",
    "radioField_lam9q83w_id": "4",
    "selectField_lb4n39p4_id": "无",
    "selectField_l75lkp2m_id": "2C",
    "selectField_l77d9e5i_id": "W",
    "selectField_l9qf3byy": "未大货",
    "radioField_lam9q83w": "M",
    "cascadeSelectField_l773a9oz_id": [
        "L",
        "43"
    ]
}

我调用宜搭获取表单数据接口的返回结构：

{
    "formData": {
        "radioField_lam9q83x_id": "无",
        "selectField_l9qf3byy_id": "未大货",
        "radioField_lam9q83v_id": "无",
        "selectField_lb4n39p4": "无",
        "textField_l75lkp2s": "OD",
        "radioField_lam9q83z_id": "无",
        "textField_l75lkp2q": "",
        "selectField_l74ppv37_id": "第一波",
        "selectField_l9w6viia_id": "件",
        "selectField_l74ppv35_id": "夏",
        "cascadeSelectField_l773a9oz": [
            "null",
            "null"
        ],
        "selectField_l74ppv37": "第一波",
        "numberField_l9w75awr_value": "",
        "selectField_l74ppv35": "夏",
        "radioField_lam9q83t_id": "无",
        "textField_l74ppv39": "连衣裙",
        "selectField_l75lkp2o": "吴沛衍",
        "radioField_lam9q83y_id": "无",
        "textField_l74ppv38": "OD23ML7046",
        "numberField_l9w75aws_value": "",
        "selectField_l9w6viia": "件",
        "radioField_lam9q83w_id": "M",
        "associationFormField_la0ohs6o_id": "\"[]\"",
        "selectField_lb4n39p4_id": "无",
        "selectField_l77d9e5i_id": "梭织部",
        "selectField_l9qf3byy": "未大货",
        "radioField_lam9q83w": "M",
        "cascadeSelectField_l773a9oz_id": [
            "连衣裙",
            "梭织连衣裙"
        ]
    },
    "formInstId": "FINST-DK866Z91ZXV69R0S6Y6A4ALQ4T7Q2AKOVR8CLXN7",
    "modifiedTimeGMT": "2022-12-29T15:36Z",
    "originator": {
        "name": {
            "nameInChinese": "宜搭平台",
            "nameInEnglish": "yida",
            "type": "i18n"
        },
        "userId": "yida_pub_account"
    }
}

我的问题是：

1. 为什么我传入的数据和返回的结构根本不符 1.1 比如 cascadeSelectField_l773a9oz_id 字段我明明传入的是 ["L", "43"] 返回值却是 ["连衣裙", "梭织连衣裙"]
2. 我的数据结构是按照官方文档传入的，为什么保存后单选框并没有选中 2.1 比如 radioField_lam9q83w = M, radioField_lam9q83w_id = 4，点击数据详情编辑，得到如下
3. 原始的拉下单选框是带有颜色的，手动添加后展示也是有颜色的，但是通过API的方式都变成了灰色
