Hello,
I’ve the following problem when exporting my score as PDF (I’ve created a small example included here).

Instead, if I export the score as a PDF, in the Apple Preview app it appears correct, but when I print it is totally different:
I’ve just installed Acrobat Reader DC, and printing from it produces a right page. So the problem appears only when printing from Apple Preview.
