Printing Duplicates on Mac

I'm using MuseScore and Mac 12.6.2. When I print a MuseScore document, I end up with significantly more pages printing than I requested. For example, I just tried to print three copies of a single-page score, and instead, I got 9 copies. (Interestingly, my printer groups printing jobs together, and for this, it printed as three groups of three pages.) Any idea why this is happening, or what can be done to resolve it?

It's worth noting that this only happens when printing directly from MuseScore. Exporting it as a PDF and printing it—no problem.

I'm pretty sure it's not the printer, by the way. I have a Xerox at the church where I work and a Brother at home, and both have this problem.
