Re: More Flow Direction stuff...
The Coda signs before measure 25, just before the 2nd ending, are the reason why it gets back to that measure. You should remove them.
The Coda's before measure 26 are OK, but you also have to remove the 3rd ending.
Unless you just want it for visual effect, two Coda locations in the same song is always wrong. There is no 'Goto Coda 2' in NoteWorthy, and no amount of creative Flow nesting will change that.
