The technical status of the aircraft is grouped into "blocks" on the status page. This is designed to help you separate what is a limitation (top left, usually blue) vs. a procedure vs. Information (bottom left, green), etc. In the attached picture, you can see the various groups and how they are separated. These groups are separated by a line, but that does not mean they aren't logically related.
In regards to the SHUT DOWN: it is confusing but remember, the status is a READ not a READ & DO. Landing distance computation comes later, during assessment. Reviewing the FCOM is not required if it delays landing but it can clear things up in this case.
