Parts and Brackets

When you create a part for some reason a bracket travels with it and there is no need for the bracket to stay on it
Could you please come up with a way of getting rid of tis bracket on a part and also can you have a way that when you change a score it also changes the parts accociated with it

And also (sorry for all the things) when a volta is added to the score it only shows up on the top score of a part could this be fixed up aswell

Thanks Heaps
