Resolved in: WooCommerce Multilingual 3.4.4

Symptoms

Steps to replicate
– Create a variable product with 2 variations
– Create a coupon that applies to only one of the variations
– Add one of each variation to the cart on the front end
– Apply the coupon

Expected result: the discount for the product variations that the coupon refers too is applied.
Actual result: the coupon is applied for both products so double the correct amount is subtracted

This happens in certain situations when using coupons that apply only for specific variations of some products.

Workaround

Use WooCommerce Multilingual 3.4.4-beta1 (under Account -> Downloads)
