Multiple recipe ingredients

[Eep²]

I'm trying to streamline the recipe list and weed out the duplicates that only have differences of one ingredient. Unfortunately, I don't think PZ can handle multiple ingredient amounts because the console shows an error of

java.lang.NumberFormatException: For input string: "100/HCCornredseeds"

when I try to merge Hydrocraft's "make vegetable oil" recipes from:

recipe Make Vegetable Oil
    {
           SkillRequired:Cooking=5,
        HCPumpkinseeds=100,
        HCWoodenbucket,
        keep HCOilpress/HCOilpress2,
        CanBeDoneFromFloor:true,    
        Result:HCWoodenbucketvegoil,
        Time:1000,
           Category:Cooking,
           OnGiveXP:HCCooking_OnGiveXP,
    }

recipe Make Vegetable Oil
    {
           SkillRequired:Cooking=5,
        HCCottonseeds=100,
        HCWoodenbucket,
        keep HCOilpress/HCOilpress2,
        CanBeDoneFromFloor:true,    
        Result:HCWoodenbucketvegoil,
        Time:1000,
           Category:Cooking,
           OnGiveXP:HCCooking_OnGiveXP,
    }

recipe Make Vegetable Oil
    {
           SkillRequired:Cooking=5,
        HCCornseeds=100,
        HCWoodenbucket,
        keep HCOilpress/HCOilpress2,
        CanBeDoneFromFloor:true,    
        Result:HCWoodenbucketvegoil,
        Time:1000,
           Category:Cooking,
           OnGiveXP:HCCooking_OnGiveXP,
    }

        CanBeDoneFromFloor:true,    
        Result:HCWoodenbucketvegoil,
        Time:1000,
           Category:Cooking,

    }

    }

recipe Make Vegetable Oil
    {
           SkillRequired:Cooking=5,
        HCCornblueseeds=100,
        HCWoodenbucket,
        keep HCOilpress/HCOilpress2,
        CanBeDoneFromFloor:true,    
        Result:HCWoodenbucketvegoil,
        Time:1000,
           Category:Cooking,
           OnGiveXP:HCCooking_OnGiveXP,
    }

 

to

recipe Make Vegetable Oil
    {
           SkillRequired:Cooking=5,
        HCCornblueseeds=100/HCCornredseeds=100/HCCornwhiteseeds=100/HCCottonseeds=100/HCPumpkinseeds=100,
        HCWoodenbucket,
        keep HCOilpress/HCOilpress2,
        CanBeDoneFromFloor:true,    
        Result:HCWoodenbucketvegoil,
        Time:1000,
           Category:Cooking,
           OnGiveXP:HCCooking_OnGiveXP,
    }

 

Why can't PZ handle multiple ingredient amounts or am I doing something wrong?
