I looked into it, and it seems like this should be fixed in the next updates of ARCHICAD 20 (70xx) and ARCHICAD 21 (50xx) to some extent. They both should be released this month.
In this update we tried to fix some reasons that can make the layout books faulty, but there might still be some issues left. If after installing the updates you still run into the problem, please let us know, so we can look into what might have gone wrong.
An open & repair should indeed fix the problem anyhow (this is a fix for the already faulty state that we included in the current updates).
