Because they amplify wavelength they are given.Anime ran out of budget or something. Not enough time to get to the end of the arc, etc.

ACTUALLY~~~~~ It was due to the manga had not yet ended and had a great deal to go still, in fact it only ended august of last year, so much like original anime for full metal alchemist they went and made their own ending. I personally hope that means we can expect a 'Soul eater: Brother Hood' ( I'd like the name to be something like 'Soul Eater; Second Course' ) in the future now that the manga has finished.
