Haven playing in reverse order

I'm trying to watch Haven on global on my Roku box. But it keeps playing in reverse order. When I finish episode 4 instead of going on to 5 it'll start playing 3.

So I have to stop it, exit, find the show again (which has reset to its default season 1 episode 1) then I have to scroll through all the episodes to find next episode and play that. And then when that episode ends 40 minutes later I get to go through it all again because instead of playing episode 6 it will start playing 4. 

Been doing this all week. I have reset the box. I'm almost through season 2 and it does this for every episode. Is it just my box?
