管理产品中没有显示所有类别？

After I click on Edit link in product grid. In categories section I am getting only one category. But I have lots of categories in store.

If I am going to add new product, all categories are showing.

Existing product, If I want to change subcategories. Its just showing only one always for every existing products.

Maybe these categories are not visible in the same storeview that the product is.
