I have seen a double question from the same user: 1 and 2, and reported it.
But looking at the profile of the same, I see only the old question, like if the new one didn't exist. Is that an edit of the other, it's a refresh problem or what?
Those are two different users (see the user IDs in the urls), though with the same display name and gravatar. They are almost certainly the same person, so a moderator will likely merge the accounts which will remove this discrepancy.
As Fabian pointed out, those are two different users. One is unregistered, while one is a registered user who also has an account on Stack Oveflow.
It seems that the user attempted to edit their question, but was not logged in.
I've closed question 1 as a dupe and merged it into 2. I also merged the unregistered user into the registered user. Now, both questions show up under the remaining user:
