Override not working in languages

Hi,

I started translating a few strings in languages and then I tried to put the file in the bottom field (override) in order to apply the changes. I also shared the changes with your software department. But as I can see the override does not work. It does not recognise the changes and it the frontend it shows the main title fow each field. I mean it shows HIKASHOP_LISTING_COMMENT or HIKASHOP_NO_COMMENT_YET although I translated it. I used notepad++ to make the changes.

What should I do in order to recongize all the work I've done?

If I load the latest version in shows me everything correct but in english. When I put the new strings in override it does nothing. Still in English. If I put the strings with my changes in the main field it gives me the titles I mentioned above.
