Android MvxExpandableListview第一项在重新绘制之前不可单击

我有一个MvxExpandableListView，其中包含一个带有项目的MvxRecyclerView。 它得到了正确的显示，但是当我加载列表时，第一个MvxRecyclerView中的项目是不可点击的（它们的显示也略有不同）。然后向下滚动一点，使项目不再可见并再次向上滚动时，我可以单击它们并显示所选项目。当我选择其他项目之一并通过“后退”按钮向后导航时也是如此

这里怎么了

我可以获取MvxExpandableListView的Github链接吗？我将该链接添加到我的项目和问题的MvxExpandableListView中。
