When you use the {@flowTitle@} token, it specifically looks for the first music frame on the page in order to show the appropriate title for the flow shown in that music frame, so if there’s no music frame it can’t do this. Instead, you can use the {@flow1Title@} token instead, which would show the title of the flow numbered 1 in the Flows panel in Setup mode, without needing there to be a music frame there as well.
