Spells: Dispell from npc's

[Zoesha]

Doesn't seem to be working correctly. Example: I was grouping with a few people and tanking on my monk, I had about 12 buffs casted on me. I had a mob cast root on me which was the top slot override at the time (had sow on) then he casted dispell on me again and instead of removing the top slot buff/debuff it removed my second slot buffer which was another beneficial buff. I have had this happen several times with other buffs/debuffs on and instead of removing the detrimental buff it kept on removing the beneficial buffs. Doesn't seem to be working as intended or as how it would work for a player casting buffs / dispell on npc's.

Noticed this on red, not sure if it's doing the same thing on blue.
