MuseScore 4 save as
So far I have always created the parts of a score and with "save as" I have created parts independent of the score itself. I used this procedure, for example, to extract the Organ part from the Continuo part while retaining the numbered bass and the Cello and Violone part, where I could delete the numbering without damage. In MuseScore 4 this procedure does not make the part independent, so if I delete the numbering from the Cello part, it also deletes it from the Organ part and the score. Is this a limitation of the software or is there a procedure that I have not found?
