I am trying to customize the accidental size for alterations through Engraving Options->Chord Symbols->Project Default Appearances->Edit
I have added a customization for Bb7(b9#11) that increases the size of the b and # in the b9 #11. That works fine. Now I try doing the same thing to increase the size of the # and b for Bb7(b5#9). That works, but after doing that, my Bb7(b9#11) chord has now changed all by itself to Bb7(b5#9), which is certainly a different chord and should not be happening automatically. What am I doing wrong? Is this a bug?
Project is attached. The two chords are both used in bar 12.
