Can't change badge to 2nd tier

I apologize if this is a re-post, i could not find it anywhere.
I've been attempting to rank up my soldier badges and ran into a little problem.
I have earned the second badge (almost 3rd) and it won't let me set it as my main badge.
It's stuck using the 1st Soldier Badge no matter how many times i try to change to my 2nd tier badge. It takes 700 kills to reach the 2nd badge (i believe) once the bar maxed it just stayed there. It still shows that i'm "earning" the next badge (tier 3) but still won't let me change to badge 2.

Any fix to this? It's not a big deal, i understand, but it is mildly irritating.

Any and all insight would be helpful!
