Don't know where you're located, but my first thought is the time difference...Auctiva and Ebay are in California, Pacific Standard Time. If you listed at YOUR time, that could cause a discrepancy.
Your listings will ALWAYS show on your My Ebay page...if they're not there, they haven't posted (yet). Events in Auctiva will tell you if there are any errors in your listings that would prevent them from posting...your Events look fine so I'm guessing it's the time difference.
