Time machine backing up wrong partition (pic inside)

So I set up my time capsule tonight, and about a few days ago I reset my computer to have a fresh start. So it did the 26 gig sized back up. During this I decided to partition the TC so I can just store all my .NEF files for photography that take up a bunch of random space on my MB PRO HD.

I also did my wifes MB PRO no issue.

Now When I do my back up, it is trying to force the backup on my Partitioned drive and make me do the initial backup again. I dont want this.

I want it to do the top one not the bottom. When I go to select a drive, two are available, (says remove disk or use this disk) so I can remove and use and to no prevale.

Any idea what I am doing wrong? I attached a picture of what I am talking about below.

Thanks a lot for the quick reply. Will try that!
