Why does he have so many reserves????

[Saransh Vatsa]

Hey,
seem to be creating too many threads today but I actually had time and so thought of putting up my screenshots as I seem to be losing them!!!!
So, this guy has 2 Subs that is S6 and S7 and has about, well, u count how many, Resserves. But how, I refreshed the game a few times and it remained like this.
Why is it so???
