Hello,
Thank you very much for choosing our theme and for contacting us.
Here is a video tutorial on the other theme, however, the way is the same that should help you translate your website texts with a Loco Translate plugin https://www.youtube.com/watch?v=D3NsDdMzsls&list=PLMw6W4rAaOgKKv0oexGHzpWBg1imvrval&index=3
Please check the video tutorial to see how to save the translation file correctly. Not to lose them during the update.
When you translate Woocommerce strings, you should translate them in Loco > woocommerce >
Please synchronize your translation, and clear the cache, let me know if you still have the problem.
Best Regards
