Basically, two things.
1. The zone bug is in effect for Evasive Maneuvers (toggling corrects this until they patch a fix).
2. The Evasive Maneuvers Defense buff always shows up in the power attributes, even though the buff acts as it should based on the patch notes. This appears to be a display glitch.
Aside from both of these minor issues, Evasive Maneuvers appears to be good to go.
