Auto relist checkbox disappeared

Has anyone else noticed that for the past month the 'auto relist' checkbox will disappear or be unticked (even though I know I tick it for all my listings). I usually have to click 'revise' my listing once or twice again for the checkbox to reappear. I now even check the night before my listings end to make sure they're still set to auto relist. Glitch or ebay being dodgy?

 

I saw on the board that this happened a couple of months ago to some users, but it's only recently started happening to me as well. Smiley Frustrated
