Google Firebase上事件计数和属性计数之间的差异

Question

我已经使用Firebase已有一段时间了。事件及其属性计数显示良好，但是当我今天检查事件时，事件计数和属性计数之间存在差异。例如：-（下面附有图片）

This is for the date range of 1st October 2019 - 14th Nov 2019. It shows the event count for "BuyOrder" event

This is the attribute data for the same data range, as you can see the number doesn't add up with the event count

Similarly for the same data range, "AddFund" event.

Same issue with this event and its attribute

对于所有属性，数据仅从11月13日开始收集。 1st October-12th November Attributes Count 但是对于一些事件，事件和属性计数是匹配的。例如：-（下面附有图片） For "Login" event

Attribute and event count mathces

有人可以帮助我了解它，为什么会发生，为什么会发生以及如何解决？
