Metal Press (Limited Stages?)

[CyanideX]

This is the json file I have in my metalpress config folder:

[
{
"input": "minecraft:iron_block",
"output": {
"item": "appliedenergistics2:item.ItemMultiMaterial",
"damage": 19
},
"amount": 20
},
{
"input": {
"item": "appliedenergistics2:item.ItemMultiMaterial",
"damage": 19
},
"output": {
"item": "appliedenergistics2:item.ItemMultiMaterial",
"damage": 15
},
"amount": 5
},
{
"input": {
"item": "appliedenergistics2:item.ItemMultiMaterial",
"damage": 15
},
"output": {
"item": "appliedenergistics2:item.ItemMultiMaterial",
"damage": 13
},
"amount": 5
},
{
"input": {
"item": "appliedenergistics2:item.ItemMultiMaterial",
"damage": 13
},
"output": {
"item": "appliedenergistics2:item.ItemMultiMaterial",
"damage": 14
},
"amount": 5
}
]

The iron block converts to the press (meta 19), the press converts to the next stage (meta 15), then fails to continue down the line. Removing the first two recipes will allow the others to continue but it seems to be limited.
