Hi - had a reply from Support they say...
"Unfortunately the problem is at our end, but we are aware of it and working at it.
If you see an item in your account which does not belong to you or appears to be unfamiliar, please remove it immediately.
If you see an item that does not match the eBay description, please remove the item and then enter again."
Removing and re-entering made no difference. I didn't get the reply until after the auction had close (it was over the weekend). As it happened I won the item (x2), BUT AS didn't see the previous bid and enterd my MAX bid from the start. I won ! But I think I've ended up paying about £20 more /item. My win history for similar items today show I was wining well below my MAX bid.
The moral is - if you see this problem appear and still bid in the auction - make sure you have a MAX bid that you would be happy to pay(as you always should have!)
Regards,
Andy
