Article Why are counts for Suggested and Verified Answers different on these two reports?

How come the following two reports, for the same Forum, are giving me different calculations for the exact same time period? 

These reports are actually reporting different information. 

The report on top is counting each reply that has been identified as a suggested or verified answer. The lower report is counting the threads that have one or more suggested or verified replies.  Since a thread may have more than one suggested or verified answer it is expected that these numbers would be different.
