Why does my script prompt a decal purchase instead of a clothes purchase?

In my game I want to script a buying prompt where a player can buy clothes off of a mannequin. I have everything set up for the script to work, but for some reason when I test buying clothes outside of studio on the published game, it would always return "this item is not currently for sale." The image is never of the full item but the decal that the item was based on. I don't know why the script sees my assets as decals instead of clothes. Also, the script can never load in the ImageID, and I don't know why. Help?!?

this script would load in the info from the clothes to a gui

OpenItemCard = game.ReplicatedStorage:WaitForChild("OpenItemCard")

function OpenItemCard.OnClientInvoke(ID,Body,ItemType,GroupType)

    local Asset = game:GetService("MarketplaceService"):GetProductInfo(ID)

    local InfoBox = Card.InfoBox
    local ReXxInfoBox = Card.ReXxInfoBox
    local OutletInfoBox = Card.OutletInfoBox

    local Price = tostring(Asset.PriceInRobux)
    local ImageID = tostring(Asset.IconImageAssetId)

    local function GetItemInfo()
        Card.InfoBox.Header.ItemName.Text = Asset.Name
        Card.ReXxInfoBox.Header.ItemName.Text = Asset.Name
        Card.OutletInfoBox.Header.ItemName.Text = Asset.Name
        Card.Price.Text = Price.."R$"
        Card.ItemImage.Image = ImageID
        Card.Creator.Text = Asset.Creator.Name
        Card.ItemInfo.Text = Asset.Description 
        print("Gathered Item Info for Card: "..Asset.Name)

    end

end

    local function TransferID()
        Card.ID.Value = ID
        print("Transferred Clothing ID: "..ID)
    end

script inside the mannequin

Adornee = script.Parent.Parent.Parent.AdorneeAnchor
ID = string.sub(script.Parent.Parent.Parent.Body.Shirt.ShirtTemplate, 14) -- change if it does not fit the correct type of clothing
ItemType = 1 --(1 for shirts, 2 for pants)
GroupType = 1 --(1 for ReXx Studios, 2 for ReXx Outlet, 3 for Other)
script.Parent.MouseClick:Connect(function(plr)
    print("Click Detected")
    game.ReplicatedStorage.OpenItemCard:InvokeClient(plr, ID, Adornee, ItemType, GroupType)
    print("ItemCard Loaded")
end)

Script inside the ImageButton

script.Parent.MouseButton1Click:connect(function()
    local ID = script.Parent.Parent.Parent.ID.Value
    local player = game.Players.LocalPlayer
    game:GetService("MarketplaceService"):PromptPurchase(player,ID)
end)
