iPhoto 9.4 update very buggy - HELP !!

Prior to installing iPhoto 9.4 three days ago I was using OS X 10.8.2 and iTunes 10.7. These updates were installed without any problems and upon launching iPhoto 9.4 it requires that the library be upgraded and I dutifully complied.

Problem #1

I noticed was that when confirming potential Faces the widow displaying the faces does not scroll when displying faces only. It does scroll when displaying the photos - a selection possible with switch in the top right of the window.

Problem #2

A more serious problem was that when syncing my Apple TV (1st generation), iPad 2 and iPhone 4S (both with iOS 6) the Photos tab in iTunes displayed extra events that do not exist (the names indicate old previously deleted ones). In addition, there is a long list of spurious (never existed), and empty events that are named with dates in the past month. As an example there are 6 events with the name "August 14" and they are shown to be empty. These extra and spurious events are only visible in iTunes when the Photos tab is selected when syncing my Apple TV, iPad or iPhone. None of the these extra events sync to any device even when selected, likely because they are empty.

Problem #3

When displaying Events on the Apple TV, iPad or iPhone, they used to display in the sort order selected in iPhoto (View/Sorted by...). As an example I had them sorted to disply by date and descending, so that the most recent Events were visible at the top of the screen. When synced, they now display by date and ascending, regardless of how they are sorted in iPhoto. In addition, the list of Events displayed in iTunes appear by date/ascending and this is how they appear when synced.

I have never experinced such a disasterous update to any Apple software before. I am in the proccess of restoring my older version of iPhoto and its librayy in the hope that this will fix these problems. Any suggestions from someone wiser than myself are welcome.
