Magento

I have tree categories like this:
- 1st
- - 2nd
- - - 3rd
so 1st is parent for 2nd, and 2nd is parent for 3rd.
1st has no custom layout and displays as catalog.xml said.
2nd has custom layout, with one changing of template file (action method=”setTemplate”)
3rd in some unuderstandable reason gets layout from parent and ignore any “Custom layout” settings.
Magento CE1.7, ofc, no cache.
If i enable template names (in developer section of settings) - it writes me, that i’m using correct template file (for 3rd), but reality is bit different - template is not correct (template from 2nd category) - I see this by generated HTML.

any suggestions?

fixed.
1st time I created subcategory in default webstore.
so I recreated category for all webstores, and all worked.
