“Post Comment” and “Leave a Reply” in WPML

Hello,
I have found few topics related to my case, but they didn’t work.
As I found in one topic, in the settings Default Form I selected in WPML settings all custom fields to be “Translate”. And I see in the string translation same two strings, default and wpDiscuz, “Leave a Reply” and “Post Comment”. I translated them separately, and also tried to translate them both at one time. No effect. Could someone help me?
I use Astra theme.
