The direction of the broken beams is correct in 6/8 but incorrect when written as triplets in simple meter. This has been a problem in Finale since forever. I know it can be corrected with the Broken Beam tool, but is it perhaps time to fix this?
This problem also exists in voiced linked parts, EVEN IF the score and master part are correct. I've just run into this in 26 with a doc created in 25. The score and master part broken beams are correct, but the voiced linked part has the stubs backwards. Of course, since it's a voiced linked part, nothing can fix it.
