Bought 3 shares at a total price of ~400$ but total allocated is 75$. What am I missing?

Okay, needleless to say noob trader here. Downloaded AvaTrade app from the app store, registered and put 400 euros in to see how it all works. I bought (at least I think I bought):
* 1 share NVIDIA 183$
* 1 share AMD 100$
* 1 share Nike 120$

However, on the my open positions it says that I have equity of 400$, available 320 and total allocated 75$. How does that happen and what did I do wrong?
