Category and Sub-category

Hello to Everybody!

I have a problem related with adding of Sub-category.

I created Main-category and I tried to attach some Sub-categories to.
Main-category: A
- Sub-category: b
- Sub-category: c
- Sub-category: d

So, when I go to Products > Edit product > tab Links > Categories. I tried to type the name of categories, but it's appear only some of them (Main-category A plus one of the sub-category), but not all as it should be.

P.S.
The problem was related with the Limit of categories, and it's solved Thanks to:
