Try a Tools - Database Check, check all the options and click on Check. Once complete checkout the log file (Viewlog) to see if anything was fixed. If that doesn't help make sure you are running the latest hotfix S114 available from http://support.cadence.com - Software - Download Software - Windows tab then SPB166.
