Hi,
This is our template's fault. The patch is very easy though. This problem has been reported in one of the topics and we provided the solution for it.
I guess you found that topic (or you figured it out by yourself), because i am seeing category description is also being displayed on this page:
moreserebra.ru/stol-serebro/posuda-chaj-kofe
I am marking this case solved, and closing the topic for clearance.
Regards.
