Typing Do7 returns a C7

I ran into an odd problem today. When I use Shift-Q to bring up the chord popover and type Do7 I get a C7 instead. However, if I type in Ao7, Bo7, Co7, Eo7, Fo7, or Go7 I get the correct chord.

When I look at Library >> Chord Symbols I can see three chords defined: Am, Bbm/C, and F/C.

Is there anything else I can check? I’m guessing a definition is mucked up somewhere.

Typing Dmin7 will work. But, I have gotten accustom to using the letter o for fully diminished 7 chords.

The issue seems to be embedded with the template I use (attached).

Chord_Input_Issue.dorico (1.4 MB)

It’s because Dorico is recognizing that input as the solfege do, which translates to C.
