You may need to disable Photo syncing to the device and sync, removing existing sync content and settings. If that doesn't do the trick, the next step would be to remove the iPod Photo Cache from your iPhoto Library's contents. Both of these steps are detailed in the following article.
If you're still not seeing Events as an option under the Photos tab, you may need to repair your iPhoto Library.
All the best,
