I have discovered that in the Logos King James Version, YHWH is not written as LORD, as is usual, (e.g. in Is. 51:22, where both forms of Lord occur) yet the Authorized Version in Logos has LORD. The reverse interlinear of the KJV has it correct, but the AV does not have a reverse interlinear. Again, in Is. 52:4, where GOD is YHWH, it is written God.
Is there any special reason for this?
