VST plug in shifts stereo timeline

Hello all, I've searched through the posts and can't find an answer to my problem.  I have a VST plug in that I use (Manley mu stereo limiter) and when I use it on my mixed down stereo project, it shifts the timeline ever so slightly, so I have one channel a bit ahead of the other channel which you can hear vividly.  The track sounds fine with the Adobe dynamic effects and keeps the timeline perfect, but can't seem to make the VST plugin work.   I have a screen capture below that show what happens to the stereo tracks after I use the plug in.  You can see one channel preceeds the other.  Jim
