It's look something wrong with category page template or with my site =)
First of all if I fill category description Virtue theme show it twice (under category name).
Another one it's not showing 'Read more' (category page) link if I use '<!--more-->' tag. If it's just excerpt without tag 'more' everything OK except russian translation. It's using word 'Продолжено' that is not correct in this case. Продолжено is adverb and we don't use it in reading context at all.
It's more correct to use combination 'Читать далее' (like at Home page) or just далее or продолжить.
