Magic Bullet Looks 2 and FCPX (First time using looks)

So am I just retarded or what? This is my first attempt at using magic bullet looks 2. I performed my inital white balance correction in fcpx and then added magic bullet to the clip, but when I go into Magic bullet, the changes I made in fcp dont carryover to magic bullet. did I jusst waste a shit ton of time white blancing and matching my shots in fcp? I was under the impression that the corrections that I make in fcp would carry over to magic bullet where I would then grade my film? Any intel would be great.

Also, if I am to just white balance, color correct and grade my footage all in Magic Bullet, is there a duel viewer option or anything for shot to shot matching? Seeing as you only have one clip at a time in Magic Bullet, it seems like I must be doing something wrong because it doesnt seem logical to not be able to view another clip for matching purposes.

Please help me

I should note that I currently am only working with one monitor. But still. seems strange
