Well, I am
And yes, it's how it works. The reason is technical (series info go into the database with the book, but the entry is not created when you send the book but when you disconnect your Kobo and it processes the new content). So, when you connect it again, the first step is to check metadata and to correct the missing / wrong ones (series, for example).
So, what I do is always the same: I connect the Kobo, send the books, disconnect the Kobo and, when the main screen appears again after processing content, I connect it again.
And sorry but no, you can't show any additional info in a fourth row.
