[Решено] Deleted string cannot be restored

Background of the issue:
I've deleted a string in hopes to remove a faulty translation in the frontend. But that didn't help and the translation stayed. Now, I'd like to recover the string so I can just put something in like "." or " ", so basically nothing is shown. But I cannot find the string anymore (I've tried searching/scanning for it, including translations and even searched in admintexts).

Here's what I've tried: скрытая ссылка
If bubbles urges you to create an account, open it in incognito

Symptoms:
Deleted string cannot be restored.

Questions:
How can I recover a deleted string in WPML?
Why does the translation remain after deleting the string?
