Translate issue

These are all translatable strings. Make sure whatever tool you’re using for translations is looking at all files: these strings are in the template file.

I’ve translated those strings into Finnish here on Translating WordPress, and the translations appear fine. As you can see here in the GitHub repo, all those strings are printed with translation functions, and all have the correct domain. Everything is set up correctly.

What if you add the translations to the WordPress.org translation system? That works.

I recommend contacting Loco Translate support if Loco Translate cannot translate these strings correctly. I can’t help with Loco Translate; I don’t use it, and I don’t know how it works.
