In the key of G♭, most B notes are natural instead of flat

[ReginaldBuren]

In the sightreading.training app, in almost all keys, the notes follow the key signature as normal, with no accidentals. But in the key of G♭, approximately half of the B notes have the ♮ accidental, which overrides the key signature. See screenshot attached.

G♭ is the only key that behaves this way. I think G♭ should behave like the other keys, i.e. no accidentals at all. Or is this intentional?

Hi, if you play in that key you'll notice that there is no C♭ so my guess is that all of the C♭ were replaced with B♮.

I had the same issue with a B♮ and a B♭ at the same place so impossible to read without looking at the number of the notes in the chord in order to compare it with your own settings.
