Soccer pick

Can someone explain this to me please. 

I bet $200 on the under in the Roma game today. At least-2.25. -130

should of paid $170? Correct?  They gave me half $86. 

@Dacmass

 That's the Asian total.  Basically when you bet under 2.25 half your wager goes on under 2 and the other half on under 2.5.  so half your wager won and half pushed hence why you only got half your expected win

Hope that explains it

@icemantbi

 So if it was 2.5 I would have won $170?

I’ll have to look out for that next time. It’s always something. Thx for help. Appreciate it.
