Dear Peter,
Many thanks for your reply and suggestions.
Sorry, but happened the old story, when you are contacting support everything starting to work properly.
If talking seriously, i was facing my problem for about a month, but after my question here wordpress has been updated to the version 5.5.2 and 5.5.3, and scan doesn`t show this mistake anymore.
So, thank you very much for being available here.
I am closing the issue.
Best Regards,
Yuliya
