Hello so could someone explain or help me solve this bug?

so i'm helping some friends of mine in a star wars game i made the auto morph by team and rank but now the parts are floating if someone can explain or help me solve thank you

here is the script

local Players = game:GetService('Players')
local Morphs = game:GetService('ServerStorage'):WaitForChild('Morphs') 
local visible = false
local GroupID = ************
local recol = ''

function morph(plr, part, location, model, test)
    if plr ~= nil then
        if test == 'Morph' then
            if plr:FindFirstChild('Morph') == nil then
                local Folder = Instance.new('Folder')
                Folder.Name = 'Morph'
                Folder.Parent = plr
            end
        elseif test == 'Coat' then -- The "Coat" and "Pauld" statements can be completely ignored or removed without harming the script.
            if plr:FindFirstChild('Coat') == nil then
                local Folder = Instance.new('Folder')
                Folder.Name = 'Coat'
                Folder.Parent = plr
            end
        elseif test == 'Add' then
            if plr:FindFirstChild('Add') == nil then
                local Folder = Instance.new('Folder')
