Apparently, since other people are not able to replicate this bug (and somehow I am).
I will be providing code to replicate and proof:

My Code:
local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")
local function GetOutfitIdFromBundleId(id)
local BundleInfo = MarketplaceService:GetProductInfo(id, Enum.InfoType.Bundle)
for i, item in BundleInfo.Items do
if item.Type == "UserOutfit" then
return item.Id
end
end
end
-- Create a HumanoidDescription from the bundle id
local BundleId = 269025838427559
local OutfitId = GetOutfitIdFromBundleId(BundleId)
local Description = Players:GetHumanoidDescriptionFromOutfitId(OutfitId)
-- Create humanoid model of bundle using the HumanoidDescription
local Model = Players:CreateHumanoidModelFromDescription(Description, Enum.HumanoidRigType.R15)
Model.Parent = workspace
Create a play session and check out the mass on the right hand!
Edit: I’m guessing it has something to do with this:
