Today is eBay's maintenance day and many things go awry. Things disappear and reappear at will, a real Harry Potter day ! Some options just are not available for a while.
eBay HQ in CaliforNIA are tweaking and adding new systems, there it's early hours of the morning, so this is when their work goes ahead and things become glitchy here from time to time.
Try again a little later on, everything should be back to norm.
