Woocommerce refund processed incorrectly

Hi
There are 2 problems we’re having:
1. When we refund an order, that was paid for fully by wallet, the funds are nor returned to the user’s wallet
2. When we refund an order, that was partially paid by wallet, the funds that are returned to the wallet is the amount that was processed thru the gateway, e.g. credit card, and not the amount that was deducted from the user’s wallet
