Problem with translations

Hi! I have installed the WooCommerce and WooCommerce Subscription plugins on my website with the Audioman Pro template. The problem I have found is that some translations are not right (English to Spanish). I have a pluggin (Loco Translate) that automatically does the translations. Everything went well except a few words. I have investigated and the problem is that it cannot find the word in the template and then it cannot translate it so by default it places it in English. I have looked for the file where the translations of the theme are but I don't know how to insert what I need. Can you help me? Thanks.
