NPCs slide across the floor for no reason?

Not sure where to post this... What happens is the NPCs aren't achored and it's supposed to be that way, but even with 0 WalkSpeed they slide across the floor. These NPCs are player clones that are script-created, so I think it might have to do with the script that created them.

game.ReplicatedStorage.AddFriendChar.OnServerEvent:Connect(function(p, clone)
    local charId = p.CharacterAppearanceId
    p.Character.Archivable = true
    p.CharacterAppearanceId = clone.VisitorId
    local user = p.Character:Clone()
    user.Parent = workspace
    user.Name = "User"
    game.ReplicatedStorage.Mic:Clone().Parent = user
    user.HumanoidRootPart.Position = Vector3.new(-15.717, 12.688, -21.785)
    user.HumanoidRootPart.Position = Vector3.new(-15.717, 12.688, -21.785)
    user.HumanoidRootPart.Orientation = Vector3.new(0,0,0)
    --user.HumanoidRootPart.Anchored = true
    user.Humanoid.WalkSpeed = 0
    p:LoadCharacter()
    workspace.LoadedIn.Value = true

    wait(.1)
    p.Character.Archivable = true
    local dupe = p.Character:Clone()
    dupe.Parent = workspace
    dupe.Name = "Enemy"
    dupe.HumanoidRootPart.Position = Vector3.new(-15.717, 12.688, -31.529)
    dupe.HumanoidRootPart.Position = Vector3.new(-15.717, 12.688, -31.529)
    dupe.HumanoidRootPart.Orientation = Vector3.new(0, 180, 0)
    --dupe.HumanoidRootPart.Anchored = true
    dupe.Humanoid.WalkSpeed = 0
    p.CharacterAppearanceId = charId
    p:LoadCharacter()

    for i, v in pairs(workspace:GetChildren()) do
        if v:IsA("Model") and v:FindFirstChild("ForceField") then
            v.ForceField:Destroy()
            v.Humanoid.DisplayDistanceType = "None"
        end
    end
end)
