The two events systems, old site and new, are different and separate.
I'd recommend you post your event info in the events forumhttp://g503.com/forums/viewforum.php?f=38
the new site events list appears manual right now. So post in the forum and let's see if it gets added by someone to the new list.
don't know why the old site isn't displaying. But I think it's getting retired so I don't know how much effort will go into fixing it.
