I customized a project plan, then saved it as a Base plan and applied it to a second project. The first project includes two different associated BT projects (not ideal but necessary for this team). I specified checks involving both of the "kyx" BT projects. Now for the second project (which, as is normal, has only one BT project), the project plan contains checks that specify the second "kyx" BT. However, the "nsn" project is not related to kyx and these checks (marked red in the screenshot) are orphaned and in the way!
How can I get rid of the checks circled in red, please? In the screenshot the green circles mark tasks pertaining to the correct "nsn" project.
I tried to edit the tasks list in the Project Plan setup screen, but these "kyx" tasks don't even appear there!
