The name in those spots is YHWH. It's the tetragrammaton, and that is God's name, not Jehovah. LORD is simply used where YHWH appears, just as the NWT uses Jehovah instead. "Jehovah" is not a Hebrew word, it is Latin.
That doesn't explain anything, since there is only one God. There was, is, and ever will be only one God; no gods. If it is just Theos, how are we to know if it is God or a god? Look at John 1:6: "There was a man sent from God, whose name was John." How do we know what God or god sent John? What about verse 12 and 13, are we children of God or a god and born by the will of God or a god?
Or, are JWs are polytheists then? If there is more than one God, that is, at a minimum, bitheism. You must believe in at least two gods. Correct?
Then that means the NWT is mistranslated too at John 1:3, since they say the same thing. Glad you can admit the NWT is faulty.
It is always translated "God" in John 1:1 because that is what the context demands.
This is patently false. You even provided evidence yourself, which I have twice pointed out, that contradicts this claim. Why haven't you addressed that?
