problem viewing a product content tree

Hi! Have a problem with viewing some products & a categories tree:

pls check the product
http://solidis-home.ru/tovar/poster-k-filmu-hishhnik

the tree is:

Главная /Настенный декор/Постеры/Постеры к фильмам/Постер к фильму “Хищник”
Main / Wall deco / Posters / Movie posters / “Predator” poster

if i click the category Movie posters – it says that nothing found there
+
if going deeper to the main category – http://solidis-home.ru/product-category/wall-deco/posters

on the left menu only half of the existing categories are shown.

What i did wrong?
