I'm using v26 on a Mac OS 10.14. I'm writing for a jazz septet. Some players have an ostinato section while other parts are changing, so I'm trying to use repeats in some parts without them showing up in the other parts. Every time I add a repeat to a part, it also ends up in the score-and in all other parts. The only way I've been able to avoid this is to extract the parts that need repeats, but then different parts end up with different measure numbers.
