Coupon reporting broken with multi-currency

We have a discount coupon set up as a 30% percentage discount.

A customer purchased a product in Yen yesterday with it, and the discount amount isn’t correctly converted to our default currency. The customer’s order was for: ¥12,588 – the coupon giving a 30% discount of: ¥3,776 discount

On the WordPress Analytics, Coupons page this shows as a discount of £3,776.00(!!) instead of the correct value of approximately £30. The value is not being converted properly.

This is the latest version of your plugin with WooCommerce 7.1.0.

The pricing is also incorrect in a plugin we use Sales Report for WooCommerce.
