:SetPrimaryPartCFrame() issue

Hello, everyone!
Recently I was making house system.
Everything works perfect, but there is issue with loading house.
When I load my house, this happens


You might gonna say: “There are some troubles with data store”. But no, all furniture loads, but sometimes in “nil” position.
Here is code and output.

Code:

    local cf = House.Value.PrimaryPart.CFrame*item.CFrame.Value
	print(cf)
	clone:SetPrimaryPartCFrame(cf)
	print(clone.PrimaryPart.CFrame)

Output:

  -35.6506462, 2.50000191, -28.6019325, 1, 0, 0, 0, 1, 0, 0, 0, 0
  0, -3.40282347e+38, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1

I tried to use welding, but it was the same thing.
Any ideas?
