I am trying to delete or edit feedback I placed after I received faulty goods.  Seller has replaced item so I would like to either delete or edit the feedback I placed as per the seller's request.  Current help page is not working.  If I simply delete the item from my 'won' list will that also delete the feedback?  I think not, but there seems no way to change or delete it.

This morning,I have found listing titles, categories and shipping costs all turning out weird.  Not as I listed them at all - just gobbley gook!  Buyers saying they can't understand shipping costs.  Cannot edit them either.  I tried to edit an item that had no views (to change category) - turned out there are 10 watchers.  Anyone else found this problem?  No notifications either but with questions regarding this glitch I have to go through every one to find any questions.
