Trouble deleting products - category amount stay

[Hpeter]

Hey there.

I clear SQL with this script.

That works perfect.
Now i have no product online. But when i check categories at the backend there is a amount of products deposited.
I add a screenshot. 
Can someone know how can i clear all old categorie staff but keep them (empty) with same ID.

That SQL works for me.

SET FOREIGN_KEY_CHECKS = 0;
TRUNCATE TABLE `catalog_category_product`;
TRUNCATE TABLE `catalog_category_product_index`;
SET FOREIGN_KEY_CHECKS = 1;
