Apollo Twin UAD2 plug in latency

I have a brand new apollo twin solo, I noticed that there was latency during monitoring my guitar track. I have a guitar track, I duplicate this track and pan each hard left and hard right. As soon as you click on a UAD plug in you can hear a very clear chorus effect, pretty close to a slap back. This does not go away when you click on bypass, this only goes away when you remove the UAD plug in completely then the two track sound normal again. How do you mix with a delay on a track? This is the first time I'm sitting with this, am I missing something?? HELP!
