From the sound of it, the problem could be either Finale or the template. Which template are you using? The ensemble template should have the transpositions set to none. That would be the first place to check. If you started with the default template and built your own, selecting those specific instruments would have the transpositions set for proper notation, meaning there would be a 2 octave transposition for the bells and 1 octave for the xylo.
In either case, check in Score Manager and verify the transposition settings.
