Yet again you say, "The new Bibles" when you mean "Some new Bibles." Here is Luke 22:31 in several English translations that are newer than the KJV:
NKJV
(Luk 22:31) And the Lord said, "Simon, Simon! Indeed, Satan has asked for you, that he may sift you as wheat.
WEB
(Luk 22:31) The Lord said, “Simon, Simon, behold, Satan asked to have all of you, that he might sift you as wheat,
YLT
(Luk 22:31) And the Lord said, 'Simon, Simon, lo, the Adversary did ask you for himself to sift as the wheat,
CEV
(Luk 22:31) Jesus said, "Simon, listen to me! Satan has demanded the right to test each one of you, as a farmer does when he separates wheat from the husks.
Those translations which do not mention "the Lord" or "Jesus" in verse 31 do have that verse as a continuation of Jesus speaking to His disciples as He was in verses 24-25, which in the ESV say:
(Luk 22:24) A dispute also arose among them, as to which of them was to be regarded as the greatest.
(Luk 22:25) And he said to them, “The kings of the Gentiles exercise lordship over them, and those in authority over them are called benefactors.
It is just plain wrong to say that the new Bibles remove "Lord."
