Page breaks in Word excludes topic from the CHM file

I have a project in RoboHelp 2022. I have imported about 5 word documents in the project. I use the Microsoft HTML Help output preset.  When I create the CHM file I notice that some topics are missing from the CHM file. 
* The topics are referenced from the toc but with a '?'-prefix in the link. 

* When I click one of the ? links, information is shown in the reading pane that the HTML file is  missing.

* The missing HTML files are not really missing, they are located in the correct folders

* However, it the title tag in a "missing" HTML file a "LTR" (u200E) unicode character has been introduced.

After some debugging, it turned out that it was manual page breaks that was the culprit. Page breaks had been inserted before some Heading 2 to make the document look good when PDF versions are created. The "HTML topic" following the page break is the one not appearing in the CHM file

So what to do? I remove the page breaks and the CHM is created correctly and all topics are included as expected.

Why does this happen? Is there a work around so that I can keep the page breaks where needed?

Thanks
