I'm thinking you need to put a conventional rack on the bike instead of the seat post rack and then it will all fit together nicely...
I just saw this, didn't see it earlier. I appreciate the picture especially because it shows how you have your lock installed - I think that was what someone else suggested. I thought I would have enough exposed seat-post for this particular rack but I was mistaken... It will work for now.
