maybe it is just a reasonable limitation by unity or ri

The problem is in ReorderableArrayInspector.cs script, at line 671:
listData = listIndex.Find(data => property.propertyPath.StartsWith(data.Parent));
The StartsWith(data.Parent)) part of it caused in my and your case to fail rendering correctly the list because it was searching for "Floor Room" and "Floor Simple" and finding just "Floor" in your case, because they both starts with "Floor".

I have solved it by replacing the code with this:
listData = listIndex.Find(data => property.propertyPath.StartsWith(data.Parent + ".") || property.propertyPath == data.Parent);
