Swing in Playback affecting all flows

I have a project with 5 flows. I set the rhythmic feel on the last one to swing on playback. [“2:1 swing 8ths (fixed)”] It works fine on the last flow, but when I go back to the beginning of the project, all flows play back with swing. When I set the first one to play straight, all flows play straight–even the last one, that I had set to swing.

What’s the trick to have the setting apply only to the one flow? I have tried it many times, both according to the manual, and with a few other intuitive methods. None of them work.

Did you set swing using this procedure?
