PvP Skill "Purify" Doesn't Work When Targeting Enemies

Time: 2.56 PM GMT
Frequency: Always
World name: Cerberus
Character name: Thana Rah'thazel
NPC name: None
Monster name: None
Class/Level: Any Level 50 Class
Party or solo: Party, 8 players
Area and coordinates: Cartenau Flats (Frontlines)
Steps:
1. I used a jump pad to get into the middle area of the Cartenau Flats map
2. A WHM from The Order of Twin Adders uses "Repose" on me to put me to sleep
3. I use the PvP action/skill "Purify", which removes all detrimental effects
4. I am targeting the specific WHM that used "Repose"
5. The skill "Purify" gets used, goes on cooldown but the effect of "Repose", which is Sleep, does not get removed.
6. This has happened to me countless of times, not just this once. I can say with certainty that it has happened to me over thirty (30) times. The skill "Purify" works perfectly on Sleep if it is used when not targeting anyone. But if you're targeting a member of the enemy team or a member of your own team, the skill gets used and will go on a cooldown but the detrimental effect(s) won't be removed.
