Issues on reports when there is refund

Hi Team, there is something wrong with the woocomerce reports.

so a client made an order yesterday and we had to refund due to some reason. It works fine yesterday.
But today i notice the reports somehow refund the order I have refunded yesterday. It’s like the same order was refunded twice.
Say for an example today there is no order, the report will give -ve amount.

Can you help us on this issue? Thank you!
