I have found word in Loco Translate and did translation, all other words are working properly but when I translate items and open page I can see that translation happens for a second and then it comes back to English again.
Like i said i managed to translate rest of the page but not only that part as it always comes back to English. I have also tried to clear cache.
Please provide the screen and page URL with the problem. I do not see the problem now. And one more tip, when you are logged in as an Administrator you may see some strings in English, however the users would see the proper language.
