Thanks for your response and for reminding me about project files. The thing this time is that I haven’t been able to reproduce the problem when cutting down a chunk of the project; for some strange reason this only happens when complete and I can’t upload the whole project because of copyright restrictions I have regarding this specific project. I’ve been trying to reproduce the issue with a segment since yesterday. I’ll keep trying until I can reproduce the problem another way.
Sorry for the long delay in coming back to you about this, Josue. I’ve been able to take a look at your project, and the problem is one we already know about (our ref: STEAM-8569). The problem is that when change key from two sharps to three flats, the lower divisi section isn’t shown at that point, and this causes Dorico to get confused about the key in the lower divisi staff, causing it to think that all of the notes require accidentals. This is something we need to fix.
