自定义菜单消息推送参数异常SendPicsInfo中图片数量参数Count:0 ?

Android上没遇到该问题，都是IPhone发送的消息出现的问题，有两个疑问，贴上请求参数：

请求一：

{"ToUserName":"aaaaa","FromUserName":"xxxxxx","CreateTime":"1597792849","MsgType":"event","Event":"pic_photo_or_album","EventKey":"wechat_menu#id#14","SendPicsInfo":{"Count":"0","PicList":{}}}

{"ToUserName":"aaaa","FromUserName":"xxxxxx","CreateTime":"1597792849","MsgType":"image","PicUrl":"http:\/\/mmbiz.qpic.cn\/mmbiz_jpg\/via4eiaemb3lbNeHbGJ1mRpOZI4TxFtaday9HJA","MsgId":"22874894874506911","MediaId":"AcoPlWow6uRJ5BTZnf8jtT5amc62X5qBmP2M4KDXu_FJYJALLwn1323l5LBWemR2"}

问题：

event消息中SendPicsInfo的Count为0， 但是第二条图片数据收到了

请求二：

{"ToUserName":"aaaa","FromUserName":"xxxxxx","CreateTime":"1597792869","MsgType":"event","Event":"pic_photo_or_album","EventKey":"wechat_menu#id#15","SendPicsInfo":{"Count":"0","PicList":{}}}

{"ToUserName":"aaaaa","FromUserName":"xxxxxxx","CreateTime":"1597792870","MsgType":"image","PicUrl":"http:\/\/mmbiz.qpic.cn\/mmbiz_jpg\/via4eiaemb3lbNeHbGJ1mRpOZI4TxFtadxx","MsgId":"22874896615000948","MediaId":"Wus3VttnUSuadarwFYI5_bjtYPymrdGQKSsrGSSLeAbklcFl9PAUNADKJZXC4IeS"}

问题：

event消息中SendPicsInfo的Count为0， 这个问题同请求一

CreateTime不一样，差1， 之前的规律是，同一个event消息对应的image消息的CreateTime都是一样的，如果不一样，怎么来对应event消息和内容消息呢？

以上疑问，盼哪位大神指点一下
