Issue with multiple fees at checkout

Hi there, my WooCommerce website uses the TeraWallet plugin which adds a negative fee to the cart if the customer is using its store credit. My payment gateway plugin also adds a fee. These fees work fine on their own, that is, when the other plugin is deactivated. However, when both plugins are active, one fee gets added and the other fee gets ignored. It seems that WooCommerce cart calculations are only taking into account one fee when calculating the cart total. Is anyone familiar with this issue? I would deeply appreciate any help or suggestions. Thank you!!
