H,
Thank you for your help.
For my first question, I think you misunderstood my question, I know about synchronizing the translations. What I do not know is where are those words (Please see the screenshots). Are the words from WooCommerce or XStore Theme (https://ibb.co/4tDsHNq)? If I do not know which theme/plugin do they belong to, I could I translate them?
