By default, the changes made during the Fix References process are written to the system log at the Debug level. This level provides complete information about the changes that have been made.
It is possible that you have previously set the system logging level to some more restrictive level, such as Warn, using the System Preferences screens. If so, logging occurs at that more restrictive level, and some of the detailed information is lost. When you determine the level of logging you want during Contact Sweeper operation, verify that the system logging level setting is compatible with your needs.
