eBay

When I go to look at my recent purchase on Ebay site, a pop-up comes on saying item removed. Only can see item I bought on payment details.Also happening on current listed items. Purchases are not removed from watch list either. This is not happening...

When go to look at items on website a pop-up appears on the site saying items have been removed. Not true. Can see same items on phone app. How do I stop this from happening on my computer?
