Just the same issue, others have mentioned. I get it, it's not an error, but deliberatly done so, but starting a new game, should mean starting a new game. I've player maybe 2 hours at launch, and now, after 2 years, I really would've appreciated, if I could start new, with the javelin suit of my current choice, now. Not the choice I made 2 years back, when I waited in line for hours to finally get online, and I was like, ok who cares, give me a suit and let's start flying.
You unlock new javelins after the first at lvls 8, 16, and 26.
I haven’t tried this, but did you try deleting all your pilots? Then try the tutorial again. Not sure if that would guarantee unlocking a different first javelin or not as I haven’t tested it), but considering you say that you only played 2 hours, might be worth trying.
