I saw this while working with a customer, but have not been able to reproduce the behavior.

On the Transactions page in 20.2, we see a transaction with 2 similar statements. In the statement stats list (bottom of screen shot) the statement is listed twice, however the first listing has an execution count of 2 and the second has an execution count of 0. So it seems like some of the grouping and/or display logic in the statement stats list is mixing up the stats...or is displaying the statement twice when it should only be listed one with the aggregate stats.
