Help with PowerAuras (Action Usable timer showing GCD)

[Fujiama]

Hello. I have had a problem for a little while now, and I've been looking for help from a lot of people, but in the end it didn't really help me a lot, so I thought that you mmo-champs might be able to help me out.

As the title of the topic pretty much states, my problem is that I have set up a couple of ability auras which use the Action Usable-activation. I have some screenshots here that will show you how it looks:

Here you can see the basic UI with the powerauras where they are working properly, and both abilities are on cooldown.

Here you can see my problem. Right after I have pressed Mortal Strike (you see the timer on its cooldown has just started) and I haven't used Overpower yet in this fight. As you see, the timer on the Overpower-aura shows the time left of the triggered Global Cooldown. (Mind you, this is also on the Mortal Strike aura, but I had just used the spell and therefore it shows the cooldown of the spell rather than the GCD)

Here are some pictures of the options of the auras. First the overpower aura:

And then the Mortal Strike aura:

Is there any way to fix it so that it doesn't show the GCD with the timer?
(And yes, I have been looking at the Global Cooldown thing you can tick off, but that doesn't help me at all :P)

On forehand, thank you very much.

Well, the action technically isn't usable until the GCD has passed. Seems to be working as intended.
