Key File Rebuild and Optimize removes all records.

Our Sage 100 version 4.40 server had a few files fail the integrity test with either read or write errors.  I selected OK to rebuild them but now all the records are gone.  The log file shows all the records were recovered.

Is this normal?

I can import the data via VI, but it will not update the Date/time changed fields.

Are these important to be filled?
