Wrong subtotal on the confirmation and shipment emails

I use woocommerce with WPML.
For the order confirmation email and shipment email, subtotal appears wrong.

For example, for the total of €370 + €70 + €185 with 20% discount, the subtotal should be simply 625.

However,
on the confirmation email the subtotal says
€625.01

then on shipment confirmation the subtotal says
€625.21

Any solutions?
