Not sure what the problem is...I see you have Auto-Save turned on correctly and I could see it working in your account...so, I'm not sure why you can't see it. (FYI -It does take a few seconds for it to save before the save status line shows up below the item description box on the lister page)
You may have a browser issue of some sort. I would suggest you try clearing your browser cache, temp internet files, and cookies. If that doesn't get you going, your best bet is to file a support case.
See below for how to clear browser cache (you didn't say which browser you are using):
