V$ SQL shows erratic results for extract folder

Hello

I came across a scenario where the gathering statistical table checking its value of cursor.

I have here for the first time (line 02) queries the table V$ SQL I have only one entry of the cursor.

And then when I again run same sql and checked V$ SQL again what I got is another record (line 27) for the same SQL_ID.

Yet once I check it twice more, but all I got is only two records.

I was questioning this table for this kind of scenario for a week.

But this is the first time I've had two records in the table V$ SQL for same SQL_ID

Your contribution would be very appreciated.
