Need help editing texts ( TRANSLATE )

Hello, I searched for hours without finding the answer.

I would like to modify the texts that appear above the comments (attached the photo).

I don’t want to use a translation plugin, but I want to modify these texts directly. Wherever they may be, please tell me exactly where I can find them (impossible to find them with the LOCO software, the words are not in the language files).

Thank you for your answer
