Double wheel: 60.0
Runway edge lights: high intensity
RUNWAY 9R
Latitude: 40-04.628812N
Longitude: 083-04.896163W

Two lines up there is a listing of declared distances. What does that all mean? I have never noticed it before.

Runway 27L has the same info being the same physical runway.

How can they have the full length available for landing when there is a marked tough down zone?

When in doubt, go to the primary source. In this case, it is the A/FD legend pages, under 21. Don't trust commercial sources.

Work on your flare. Maybe look further down towards the end of the runway. That might soften it right up to touch down zone status.
