When the Staff Attributes dialog box is 
 opened in a part, only staves within the part are accessible. All of the 
 settings are permanently shared between the score and parts with the exception 
 of the Staff Name/Abbr. Staff Name positioning. If the Staff Name/Abbr. 
 Staff Name is repositioned in the part, the link is broken - the change 
 does not apply to the score or any other part. Future changes to the Staff 
 Name/Abbr. Staff Name in the score for that staff do not apply to the 
 part unless the Staff Name/Abbr. Staff Name is relinked (see Relinking part items to the score). (Staff 
 Name in Parts is unchecked by default. Check this option in the Staff 
 Attributes dialog box to show staff names in the score and parts.)
