bad translation for place order button and title of Cart page

Hello, I am using Loco translate. I have updated all the plug ins. My site is in Spanish and you can change the language to English. Suddenly i have two problems:

1- When i switch the language to Spanish the standard button “Place order” on the Checkout page says “Ordering” I have no idea why or even where to find the translation, if “Place order” should be the standard language of the button.

2- My cart page has the correct name of the page i Spanish (carrito) but when I switch to English it says “Trolley” obviously a bad translation as it should say ” Cart” i have no idea where to find the string to correct the translation.

Any ideas?
