score and part don't always sync

I have noticed that certain changes that I make in a score don’t always show up in the corresponding part. For example, “showing” an accidental, either with brackets or not, in the score doesn’t show up in the part. Respelled accidentals also don’t show in the corresponding score/part screen. Is there something I can set to make that happen?

Select All
Edit > Propagate Properties

Note that respelled accidentals are not properties and can’t be propagated. If you respell an accidental in a score layout it will automatically respell in the part. If you respell an accidental in a part layout it will not respell in the score. This is an intentional design decision.
