Transposing instrument issue

Hi,

Loving Dorico so far…
I have a Score in the key of C Major. Unfortunately the Bb Trumpet part is displaying accidentals and not a key signature of D major when I’m preparing it for and actual printed part.

Additionally - there is a big number “1” over every single empty bar, like a multi-bar rest - except it’s just a single bar!

How do I fix these please?

Have you actually added a key signature of C major? Or is it atonal?

A probably atonal…

That fixed it many thanks!!

how about the single bar multi-measure rests?

Look under Engraving Options > Rests.

Thanks found it. I have no idea why that was set that way for only one part!
