Strings Translations missing fields

Hello,

I’m facing weird issue with Strings Translations page. When I have installed polylang and my theme. Also setted up 3 languages and in string translations there was showing 3 options to translate to 3 different languages. Now when I come to Strings Translations I only see my default language of website, other languages translation fields are missing, so I’m only able to translate default lang strings. I have tried to uninstall and install Polylang, then problem just gone, but that’s another problem. If I delete polylang (I mean hard delete with all data reset, because soft doesn’t work) my template lost structure (it made with Elementor), menus gone, pages, products, posts have no longer relations. There is any fix for this without uninstall or possibility to translate those slugs manually?
