Request [NEED HELP] EnderIO change Alloy Smelter Recipe

[nidico100]

Hey,

I try to change all copper ingots in my modpack to just one copper ingot, so you don't have tons of different ones in your chests.
The last thing I have to change, is that the EnderIO Alloy Smelter smelts the ores and the dust into the right copper and not the copper it currently does.
In the AlloySmelterRecipes_User.xml I added the following lines:

<AlloySmelterRecipes>
    <exclude>
        <itemStack oreDictionary="oreCopper"/> 
    </exclude>
    <recipeGroup name="Ingots">
        <recipe name="ingotCopper" energyCost="2000">   
        <input>
            <itemStack oreDictionary="oreCopper"/>
        </input>     
        <output>
            <itemStack modID="exnihilo" itemName="exnihilo.copper_ingot"/>
        </output>
        </recipe>
    </recipeGroup>
</AlloySmelterRecipes>

But this didn't work. All ores are still smelted to Thermal Foundation copper. Even this recipe isn't removed as the <exclude> command should do. Anyone can help me?
