Staff order changes when adding a staff

Hello everybody,

My appologies if this has been treated before.
Something unpractical is happening: when I add a staff to a score, my custom staff order previously made is set back to default. By consequence I also loose all bracketing changes.

Is there some setting to secure my changes?

Do you have an automatic player sorting setting selected in Setup mode (see the Note at the bottom of that page)? If so, change it to “None”.

thanks a lot!
