Different Text Frame format with same Flow (structured FM 2022)

[QuintinSeegers]

Our EDD is structured with a top level Chapter element that consists of a CoverPage element, followed by a Section element. The CoverPage element is used on the first page of the chapter, with a specific Master Page layout. The Section element starts on a new page and use the default Left and Right Master Pages. The text frames on the CoverPage, Left and Right pages all use Flow A with Autoconnect. The text frames on the Left and Right pages have a Side Head. The Coverpage does not. I\On the Master Pages, these are setup - no issues. 

On the Body Pages, all pages using the Left and Right Master Pages have the Side Head setting applied (correct). However, the text frames on the first page (using the CoverPage Master Page) are also applying the Side Head, even though it's not applied on the Master Page. When the text frame properties on the first page is overwritten to remove the Side Head, it is removed from all the pages, even those using the Left and Right Master page (which does have the Side Head applied). No matter what I try, FM won't follow the Master Page layout. Overwriting the Text Frame properties on any but the first page to turn the Side Head back on, it is also applied to the first page.

Any suggestions from the community as to why FM is not adhering to the Master Page layout?

For anyone else looking for a solution to the same problem:

Turns out that FrameMaker sees the Text Frames associated to the same Flow as a single component and not master page specific. To get this to work as required, I had to turn the Side Head option on for the text frames on the CoverPage Master Page, but make the width and gap 0.
