Two merged (child) projects not appearing in parent project TOC

[Spectrum Writing]

I am using RH 2019.0.9 to create a merged project. I have one parent project and 18 child projects. I have my folder structure successfully set up and I have ALL the child project TOCs redirected/loaded in the parent project TOC. I am getting no errors when I generate any child project or the parent project, but not matter what I do, I cannot two of these child projects to be displayed in the final merged project. I have deleted the child TOCs from the parent TOC and redirected to the parent TOC and regenerated the merged TOC, and still nothing. Any thoughts? I have attached screen grabs to illustrate the issue.

TIA,

I have also confirmed that Hide in Output is NOT selected for either child project.

OK, I had to update to a the .9 version - long story short, the merged project from which I was working was created in a Beta .9 version, and at the time that I was working this issue, I had access only to the released .8 version. I had assistance in getting upgraded to the .9 version and had to work out a few path details for some files, but now all is OK. Thanks!

As a test, could you try temporarily removing two of the working child projects from the parent toc and see if the two misbehaving ones now show up?
