Greatest Hits Vehicle Pack

I opened one of the 100K greatest hits vehicle pack and got two rare certifications? In the pack description it says it guarantees two ultra rare or better vehicle certifications. I also received a lot of rare reqs in the pack which doesn’t make sense either. Am i missing something or did I get screwed?

Any chance you already have all the certifications unlocked? Were the certifications you got in the pack for Mongooses?
