Serious Q about fighter intros

Why is it that every single UFC they will announce a guy who is clearly a striker as "a boxer and a wrestler" and then list his record as like 12-8 when it's 14-8 on the screen and 19-8 in real life?

Its like theres bizzare system in place where they count only your wins from events before your first UFC appearance but all your losses. And theres a disparity between the screen and the announcement. And Louisaeu is not a wrestler.

I still want an answer.
