Linked Blogs Problem

*I've tried emailing EC, they haven't responded

I've had my main blog http://callistasramblings.blogspot.com in EC for a while although I've just recently started getting the hang of what to do. I recently added my book blog http://smsbookreviews.blogspot.com and when I switch to that blog (making it active) I go and drop cards on tons of book related blogs and none of them drop back. I've had the people I dropped on end up dropping on my main blog instead. Some of them have applied for advertising on my main blog, even though they are book related blogs and I dropped on them from book blogs. I hope I'm not confusing anyone.

It's like when they see that I've dropped on them it puts them back to my main blog instead of the book blog to drop back. I had people dropping on my main blog when I first joined even before i dropped on anyone else and yet it's been a few weeks and still not ONE drop on my book blog one.
