Kobo Glo - Issue with book sorting

I hope this is the right place to post this. I got my Kobo Glo today and so far it works pretty well. I got all my books on the device using Calibre and it worked almost perfectly. Almost. :);)

I like my books to be sorted from A to Z. For example if the book is "The Hunger Games" I want the book to show up in my Library under the letter "T". I don't want it under "H". On my Sony PRS-T1 all I had to do to achive this was editing the Metadata in Calibre. For example the first Hunger Games-Book has the following Metadata entries in Calibre:

Title: The Hunger Trilogy 01: The Hunger Games
Title Sort: The Hunger Trilogy 01: The Hunger Games

The Second Book:
Title: The Hunger Trilogy 02: Catching Fire
Title Sort: The Hunger Trilogy 02: Catching Fire

And the same for the third. Now on the PRS-T1 all of the books could be found under "T". On the Glo the sorting has gotten a little bit messed up. The first book can be found correctly under "T". The second and third book however are sorted under "H".

I have similar issues with the rest of my library. Books with a title like "A Troubled..." are found under "T". Other that start with "A Love Story..." are found under "A". The some goes for books with "The" in the title. Some are under "T" most are somewhere else.

I first thought the Metadata was wrong but it doesn't look like it and there are all correctly sorted on the PRS-T1.

I realize that this is more of a cosmetic issue but if someone has an idea I would be thankful!
