'react-calendar-timeline' 在第一次加载时呈现错误日期的数据画布与日期标题不匹配

如何解决'react-calendar-timeline' 在第一次加载时呈现错误日期的数据画布与日期标题不匹配

我在代码中使用包 react-calendar-timeline。 时间范围为 10 天。

加载时间线后，它应该显示从今天起 10 天的项目。 DateHeader 始终正确加载，但画布显示 10 天前的项目。

这些是一些例子。组 1 在 07 27 ~ 07 29 范围内有一个项目。

但是，在canvas中，项目在08 06 ~的范围内。 first load

点击上一个或下一个按钮后，画布正确显示项目。 after click prev button

但是，在单击 prev10 或 next10 按钮后（在单击 prev 或 next 之前），画布显示项目错误。 click next10 button after first load

这是我的代码：

var keys = {
    groupIdKey: 'id',groupTitleKey: 'title',groupRightTitleKey: 'rightTitle',itemIdKey: 'id',itemTitleKey: 'title',itemDivTitleKey: 'title',itemGroupKey: 'group',itemTimeStartKey: 'start',itemTimeEndKey: 'end',groupLabelKey: 'title'
};

        super(props);
        const groups = [];
        const items = [];       
        const visibleTimeStart = moment()
            .startOf('day')
            .valueOf();
        const visibleTimeEnd = moment()
            .startOf('day')
            .add(10,'day')
            .valueOf();
        const zoom = visibleTimeEnd - visibleTimeStart;
        this.state = { groups,items,visibleTimeStart,visibleTimeEnd,zoom };
    };
    async componentDidMount() {
        const {groups,items} = await GanttData();

    };
