It's not a programming issue. It is purposely set up to do that. If you go to a library (Dewey Decimal System) to look for a book called "The Adventure", you look in "A" for adventure, not T for The. I have my books set up this way, not many people actually look for a song starting with THE. If you look it is still alphabetizing correctly by the actual sort word - in this case "adventure". If you do not want A & THE at the beginning, like stated, click The/A at end box instead on The/A at start.
Another example, if you go to a record store looking for The Scorpions, you look under S!
If you truly want THE to be the beginning word alphabetized under T, then when in the edit screen, change all of your songs that have THE at the end and edit it to be in the beginning. So in this case you will want
Adventure, The to be changed to The Adventure.
Now instead of sorting under A for adventure where it is supposed to be, it will sort under T with THE being the sort word - much more confusing IMO.
