I have a very peculiar situation that looks like it must be a bug. See the attached graphic. In the first measure of the coda, if I put a C# concert in the trumpet part (any beat), Dorico shows a sharp. There has been no key change and C# is in the key signature, so I should not be showing a sharp there. This will only confuse the player. I realize I can force the accidental off, but that should not be necessary. This behavior occurs only in the first measure of the coda.
And notice in the trombone, an F# does NOT display an accidental, which is correct. For all notes, the accidental property is off.
Any idea what is going on here?
