Sorry, I'm not sure I understand. I've tried it on the image below the Главное tab, and it works for me. If this is not the image you're referring to, can you send a screenshot of where the image is on yandex.ru?
If this is the image you're referring to though, can you send me your settings? (Export button at the top of the options page) Hopefully that will let me reproduce your problem and find a fix :)
My contact information is listed at the bottom of the addon's page.
Edit: Sorry, I hadn't seen your edit. My email(+pgp key) is listed here: https://qsniyg.github.io/
