XML import ignores Chord accidentals?

Hello everybody,

I am a beginner at Musescore. I'm using Cubase to export a melody plus chords as an XML file, including the Cubase Chord Track. This imports nicely into Musescore, with one caviat:

For some reason, Musescore ignores any accidentals in my chord symbols when importing. E.g.: If Cubase has a B flat minor (Bbm) chord, it exports into XML as follows:

   <harmony>
                <root>
                    <root-step>B</root-step>
                    <root-alter>-1
                    </root-alter>
                </root>
                <kind>minor</kind>
            </harmony>

But Musescore displays - and plays! - a Bm chord.

Is this something I can fix in Musescore? or is it something that Cubase is fomatting the chord in a different way? I have to do this for a ton of songs, so fixing it is preferable to manually going over every single chord.

Thanks for your help guys!
