Empowerment buffs

Case: Made a "Confusion Resistance" through the empowerment buffer, sadly it has a sort of tentacle darkness around itself. So i decided i should wait out the 15 min timer that it says it will last. Soon i have waited 30 minutes...
It still says 15 minutes.

Now probably there must be something i have missed, so could anyone tell me if making empowerment buffs is now a permanent thing or something?
Now normally i would not complain if we get a permanent buff, however being unable to hide the buff or delete it means that some characters now will be unplayable in f.ex roleplay.
If they are to be permanent buffs, could you the Devs please make it possible to hide them?

They wear off in 1 hour I think. It's pretty bizarre that the time in the description is still wrong.

I have to say that some of the buff effects look terrible. One of them surrounds you with a sort of nauseous green/yellow glow. On the other hand one of the others gives you cool rings round your arms and feet. (Knockback resistance I think.)

I think you can remove them from your temporary power listing manually too. Used to work, not sure if it still does... (power tab - right click --> delete power)
