Zip/Attach a copy of the original Hand history for the table with the issue*
*All original hands that are auto-imported get moved to an archive for performance reasons. Your \HM3Archive is in C:\HM3Archive by default, but you may have put it anywhere. The archive should be organized by \Network\Month\DayOfMonth (example: C:\HM3Archive\SiteName\HM3Archive\2016\07\31). It is configured in the Tools - Settings - Import menu.
