Finding the sites using the same access key

I get the email ‘We noticed that your CleanTalk Access key was used on more than one website within the last 24 hours.’ and this lists the ‘new’ website the key is being used by, but I can’t find in the account where it lists the other sites the key is being used….
The site in the email is the correct one and this is after recreated a new key so I am trying to figure out what site has somehow used the new access key.
