Please Help Me Remove Normal Cobblestone, But Not Named Cobblestones

[duhnoob1010]

on block break:
    loop all players:
        loop all items in loop-player's inventory:
            if loop-item's name is "&6&lCOBBLESTONE AUTO CRAFTER":
                if amount of cobblestone named "" in loop-player's inventory is greater than 9:
                    remove 9 cobblestone named "" from loop-player's inventory

 

So as you can see in this skript, it is supposed to remove 9 cobblestone from player's inventory. The issue is that it also removes other cobblestones that have different names. If I use color codes such as &f, &r, &e, etc, none of those removes ordinary cobblestones.
