Using Version 1.4.7.10 release
I have a dynamic group set with all of my mage cool downs.
It's hidden until a spell is on CD, then shows the aura with a hourglass timer.
Once the spell is off CD, the aura disappears.
This works with every spell in my dynamic group except Ice Barrier.
When Ice Barrier is on cool down, the aura appears but once the hourglass timer has finished, the aura remains on the screen.
What makes it even more weird - if I have several auras in my group displaying their cd time remaining, Ice Barrier aura will disappear when its cd is up in any situation as long as its not the last aura to come off cool down. If it's last or used alone with nothing else on cool down the aura refuses to disappear.
Other people have tested my auras and have the same problem.
I have attached the weakaura string I have been using
