From TFWiki:
Optimus Primal is just an exploration ship captain, one of many. He is not a high ranking member of the army.The Energon Matrix (エネルゴンマトリクス Enerugon Matorikusu) is a powerful device awarded only to high-ranking members of the Autobot or Maximal army, most often of Convoy rank.
I am drawing on several sources to paint a picture of the CGI universe Optimus Primal, and that picture simply has no matrix in it whatsoever.
I didn't say that Lio or Big Convoy sat on the Convoy Council, but the Japanese media explicitly states that Primal does. That is a different Optimus from a different and separate continuity.
And just because the Sourcebook contradicts other stuff doesn't make it any less official or any less canonical. Now who's picking and choosing to fit their argument?!
They are clearly different continuities, and different characters.
I hear you Grasshopper, but I couldn't not share that little tidbit I came across.
