Schedule config:

{
    "subject": "最新的Dashboard",
    "to": "abc@example.com",
    "type": "image",
    "contentList": [
        {
            "contentType": "portal",
            "id": 1
        },
        {
            "contentType": "portal",
            "id": 1
        }
    ]
}

I only want to send one picture. But when i select the expected portal, it automatically add two in the config json, which can not be edit.
