Flow Heading trouble

I have a project with several Flows. I want to show a Flow Header only on the First Flow. Layout Options is set to NEVER show a Flow.

I insert a Flow Heading change on page 1, but I get nothing. The only way I can get it to work is to set Layout Options to ALWAYS show Headings, and then Change the Flow Heading to None on page 2.

There is no override on page 1, but it does have a custom Master Page.

Anything obvious before I submit a file? I can’t see anything else in Layout Options that should affect it. And surely, the Change should override the Never setting?

I don’t think this particular combination of settings is supported, I’m afraid. We’ll take a look at it and see whether it’s a combination we can easily support in future.
