I cant translate text in the email settings

Actually,
I have translated all these texts in the crowdin, but if I chose the Estonian language, all the texts are in the English language, I can translate only the title, but while I am trying to translate the message then after I translate the text and click save. It saves the changes infinitely, saves nothing. If to reload the page then I get an access denied error. The Title I could translate one by one. I use cloud version of accounting

The problem appeared while pasting from the other sources, If I write down translation manually, then works fine.
