CD Bug with Warper's command skills?

Hi,

I got 3 points in warper’s spectral storm and 2 points in spectral strike.
Spectral storm has ~8s cd, but when i activate it, both (storm and strike) are on cd and strike is on 20s cd.
And i can only do spectral storm again after the 20s cd from spectral strike is over.

Is that normal?
