Prevent repeat playback

I use playback only for proof-reading. How do I prevent repeat barlines from repeating on playback? I tried this:


but, oddly, the Play n times setting does not allow you to set it to “1” (and why is that under 'Time Signatures" in the properties?)
I also tried “Suppress playback” and “Suppress on passes” under Common but those do not seem to do anything at all.

Try unchecking play repeats in Playback options.

Thanks! (That one I probably should have found.)
