Question about my dual wan setup

I am really new to Mikrotik products, but have been trying to learn them.

Anyway, my question is about dual wan. I have it set up and it “seems” to be working fine, but please have a look at the picture:

WAN1 shows little traffic in the prerouting section. Is this normal behavior?

Appreciate any and all comments.

Just to be clear, the second last one from the bottom.
