Translate theme

Hello! I have installed Polylang and Loco Translate and used them both to translate terms in the theme. But I can not find out how I can translate the “Older posts” and “Never posts” that comes up on the bottom of my category page. I think the terms are given in inc/template-tags.php so I tried to add a inc/template-tags.php folder to my child theme and change the text, but the translation did not show up.
