How do the Initiation DLC trophies glitch?

[OmegaRejectz]

I started the game without installing any patches (1.00) and I have completed 3 missions of the Combat Training with 3 medals, 3 stars on one mission in the Ranked Challenges & 2 stars on a map in the Custom challenges. (Aka I’ve almost 100%ed every challenge I can do so far) people said you can complete this without having the DLC. I’d love some help
