Orb of frostfall doesn't work

Orb of Frostfall doesn't grant Trail: Snow to my Frostvine in this game (check picture), even though it's within 5 spaces of my Doomball.

 

It used to be 4 spaces, can you check if that's the case?

 

I know for certain it used to be 4 spaces, but the description says it's 5 spaces now.

 

I meant if you can check if it's working within 4 spaces, or it's a major problem.
