Order refund and cancellation time period

Hello all.

Why does Shopify not calculate the order value of cancelled orders in the related month or year?

2 examples:

Customer order is in August and gets refunded in September the order value gets substracted from September order volume.

Customer order is in August gets refunded, by cancelling order in Shopify, in August but refund is pending by the gateway (in this case PayPal) and after ten days of pending it gets refunded in September and order value gets substracted in September.

So if this is a single case of small orders it can be ignored but if the number and especially the amount of orders is high it does show wrong results in statistics .

Some opinion for this from Shopify side?

Some shopkeeper have the same issue?

Thanks for your attention
