May be it’s a logical issue. Simply put this is the current flow: Click to register > Receive email > Click verify > Insert > then allow login since token was verified.
Instead of: Register > Login > Insert > Owner captured before insert because they are already logged in.
Or maybe its a program bug that the developers overlooked.
(I personally prefer to filter by owner as it involves the least amount of code that can allow you to get the most creative. Although, worse case scenario ---- you could always change your code logic to filter by email address instead of owner.)
