Skinned item does not display while in hands?

Hey, I'm just trying to get my head around the config on this plugin (could do with some documentation really) with that being said, ive managed to change my heli crates so that it replaces the standard m249 with a skinned varient however the item in the inventory and hotbar correctly show that its skin is applied but when i move it to my hands it just shows the default m249.

 

I've tested this with multiple skin varients and it happens for all of them... any help would be apprciated. heres my config:

 

{
"Refill Loot On Plugin Load": true,
"Container Loot Save Command": "lootsave",
"Container Refill Command": "lootrefill",
"Load Config Command": "lootconfig",
"Containers": [
{
"Entity Shortnames": [
{
"Shortname": "heli_crate",
"Enable Regex": false,
"Exclude": false,
"API Shortname": false
}
],
"Process Corpses": true,
"Process Loot Containers": true,
"Monument Prefabs": [
""
],
"Shuffle Items": true,
"Allow Duplicate Items": false,
"Allow Duplicate Items With Different Skins": false,

},

}
],

}
],
"Item Name (Empty To Ignore)": "",
"Is Blueprint": false,
"Allow Stacking": true,
"Ignore Max Stack": true,
"Ignore Max Condition": true,
"Remove Item": false,
"Replace Item With Default Loot": false,
"Conditions": [],
"Skins": [
{
"Skin": 2101133226,
"Chance": 1
}
],
"Amount": [
{

"Maximal Amount": 1,
"Rate": 1.0,
"Chance": 1
}
],
"Chance": 1
}
]
}
],
"Debug": false
}

Tested again with an AK instead of the m249, item skin registers in the crate, inventory and hotbar but will not display in your hands...
