Elite 1911 codex count Incorrect

I have a issue where my M1911 codex count is incorrect to the amount of kills I have achieved.

Dose anyone else have this issue. And can it be fixed?

And a question occured while writing it when was the codex added to the game if was later than launch during "in the name of Tsar", "Turing tides" or "apocalypse" and that is why it's has barely any progress as I was on a long break from the game.
