@markgreenhalgh,
It is most likely a glitch, but the issue might be caused if you haven't cleared your temporary internet files, and cookie cache in awhile. An update to your browser might cause the issue, but those usually affect other things as well. If you use Chrome try switching to another browser. Chrome and ebay do not play well together.
