UK Brass and SA Brass key signature bug?

Hey, I've just downloaded Musescore 1.2 and noticed that they've added UK Brass band and Salvation Army templates. Though I didn't download MuseScore for brass music I had to check out the templates.
I've tried creating blank UK Brass and SA files in the key of G and noticed that both Bb and Eb instruments have a sharp (#) in their key signatures.

As far as I can hear the instruments sounds correct if I change the key signaturefor all Eb instruments, but it would be nice if the templates automatically upheld the difference between Bb and Eb instruments.
