I have checked with Graphisoft for an answer, and it turned out that the default Room Finish Schedule in the project map is linked to Zone Stamp 01 21, and I am using Zone Stamp 02 21. I was told that 02 21 is more flexible than 01 21, but the problem is that 02 21 does not seem to have the North, South, East, and West Walls configuration that I need. So anyway, being in the middle of a project, I filled in the missing information using good old Excel.
