Problem with categories

Hi,
I start creating new categories and subcategories but in perent field does not show more than 5 categories. As you can see in the attachment files the category - Collections is not there.
What is the problem?

That list is configured to show 5 rows at most. Have you tried writting down the name of the category? Because it is supposed to show if you start typing the name. If you want to show more than 5 results on the dropdown, edit line 596 in admin\controller\catalog\category.php to the number you want :

Thank you for your reply.
Now it's ok.
