关于调用'FindMeetingTimes' API 时的响应错误结果

Question

调用“FindMeetingTimes”API 时，结果与用户的日历不同。

User's Calendar Information

请求正文：

{
"attendees": [
    {
        "emailAddress": {
            "address": "xxx",
            "name": "xxx"
        },
        "type": "Required"
    }
],
"timeConstraint": {
    "activityDomain": "Unrestricted",
    "timeslots": [
        {
            "start": {
                "dateTime": "2021-04-08T09:00:00",
                "timeZone": "Eastern Standard Time"
            },
            "end": {
                "dateTime": "2021-04-08T12:00:00",
                "timeZone": "Eastern Standard Time"
            }
        },
        {
            "start": {
                "dateTime": "2021-04-08T13:00:00",
                "timeZone": "Eastern Standard Time"
            },
            "end": {
                "dateTime": "2021-04-08T17:00:00",
                "timeZone": "Eastern Standard Time"
            }
        }
    ]
},
"isOrganizerOptional": "true",
"meetingDuration": "PT45M",
"returnSuggestionReasons": "true",
"minimumAttendeePercentage": "100",
"maxCandidates": 48

}

该用户的日历显示“13:00-14:00”时段时间可用，但响应没有，

                "timeZone": "Eastern Standard Time"
            }
        }
    }
]

}

但奇怪的是只搜索'13:00-17:00'时间段，结果会出现，

}

不知道为什么，谁能帮我查一下，非常感谢。
