Translation problem

Hi,

I bourght the pro version, and I cannot translate in french

I edit the pot file with Poedit and translate in french, and save in the language folder with the name woo-save-abandoned-carts-fr_FR.mo and/or woo-save-abandoned-carts-pro-fr_FR.mo (I tried both) but no translation is done. Neither on admin side nor on the customer emails
Of course I cleared all caches.

Can you help ?
