Payment buttons

Hello, I have 2 issues I don’t succeed to resolve.

1- The paypal button of the WooCommerce PayPal Checkout Gateway : I try to change the label “acheter” (buy). I tryed in the settings (title) and in the POT file, but still, I don’t find where to modify it. Where can I modify this label ? I named the .PO and .MO fr_FR, maybe I have to change the name by something like woocommerce-gateway-paypal-express-checkout_fr_FR ?

2- When I am in the cart, I tryied to change the label of the button “valider la commande”, and after validating the cart on the order page, I tryed to change the label of the button “payer avec paypal” (pay by paypal). I want to change the text of the buttons. I dowloaded the .PO file you give, and I gave the name fr_FR to the .MO and .PO file. Maybe this name is incomplete and I must change by something like woocommerce_fr_FR ?

How could I change thoose text on the buttons otherway if I cannot do it from the .PO ?

Thank you so much !
