DLP 16.0.1
Environment Issue
This was a peculiar behavior on the environment but forcing the parameter change helped and the recycle of services (Monitor Controller service) resolved the issue.
1. Updated the ContentExtraction.EnableMetaData parameter value to force the parameter change
2. Update the value from ON to OFF then back to ON.
Note: Saving the values on each action performed above.

3. Recycled the Monitor Controller service which would re-enable the connection with all the latest updates from the environment to Enforce.
4. Once the system is up with the connection we tested the behavior with a test word document.
5. As you have noted that the METADATA was detected on the word document.
