It does seem like an X is missing from the Country Level column (W). Can you file a feedback request to the Change Control Board with your suggestion? https://tmfrefmodel.com/feedback
A “General” section of 4 artifacts exists in each zone. Despite our best efforts over the years, getting 100% consistency in every zone for these General artifacts has been a bit elusive.
I recall when I was working on v3.0 of the model with others we sometimes used a rule of thumb, if there is at least one country level artifact in a different section of the zone, then the country level is indicated for each of these “General” artifacts, unless it seemed nonsensical. Same logic holds for site level. But I’m not certain others saw things exactly the same way.
Flagging this for the change control board should help.
