Layout Options Save as Default not working

Hi!

I’m working on creating a template that works with my particular workflow. I’ve managed to get everything right, except the “show flow headings” layout setting. I want it “for all flows” on my parts. I’ve done it and clicked on “Save as default”. Then I saved as template and didn’t work. I tried selecting one layout at a time, and saving per part. Didn’t work either when I create a new project from my template. It works with all of my other saved options, just not that one. I’ve tried even recreating on Dorico 4. Doesn’t work. How can I solve this?

Clarification: The saved defaults work for everything else, except files created with my template.

Thanks!

How are you creating new projects, via File > New or via the Hub? Because there’s a “Project will use multiple flows” option on the Create New tab/page in the Hub that, when deactivated, hides flow headings.
