Buy menu side arms and shield weird prices

So in the first round you have the "little smg" and "ghost" (from valorant) for 800 currency and the revolver and "ghost" are also 800 currency except the 2nd weapon choice actually costs 800 whilst the other one costs 400.

The shields have wierd prices, I don't know if it's intentional but the light shield is 600 i think and the big one is free which i don't understand because the big sheild is way more efficient therefor i would think the prices should be inverced
