spektral problem with stereo recording?

hello all,
so i was recording in pro tools.
i had a stereo track with a drum loop on it.
i added spektral to the track and bussed it to a different stereo record track to explore the many presets with S.D, and record the ones i liked.

I've noticed though that every time i record spektral delay onto the record track, the right stereo track has less output then the left.
in other words the wavelength is smaller-hence the volume drop and my problem. why is S.D recording higher on one side of my stereo track?
I've checked my panning and its fine.

now this happens on any S.D preset i use.
is there a reason spektral records higher on one side of the stereo track?
is there a way to remedy this?
it is the only plug in that was inserted on the track as well?

I love SD but i can't have this happening all the time.
i've enclosed a jpeg with the wavelength problem

 

no one knows the answer??

so no one out there knows the answer to this????

native instruments, etc???

its really strange. i cannot seem to figure it out?
