Translated String in the Editor Don’t Show Up

My site is still under construction so I generally put it in maintenance mode.

So, I’m using the Paid version of this plugin. I can translate show words into more than one language. From Turkish to English. But when I want to translate strings (longer sentences), everything shows up fine in the editor but the changes don’t show up in the page.

I use WP Rocket and Asset CleanUp Pro with GeneratePress Premium theme. I disabled all the plugins one by one, cleaned browser cache, cloudflare cache, added the js and css files for translatepress to not be minifed, but still had no success.

Someone from the paid support couldn’t find the issue and I would like to ask here if anyone also had the same problem? I really need to fix this issue because I will have long articles in two languages and I can’t just use a shortcode on all of them, it would be a pain in the ass. I have to get this fixed asap.

Please visit the link I attached to see the translation error. It’s the sentence right underneath the main menu saying “Ho? geldiniz! Lütfen ilk ?nce Kullan?m K?lavuzu nu okuyunuz.” (Turkish) and it should normally shows as “Welcome! Please first read the User Manual.” But it doesn’t seem to completely translate it.
