Bug in "Analyze Data" tab

I tried the "Analyze Data" button in the Home tab. I gave it a column of integers and it gave me a histogram. The problem is that the histogram has the wrong counts. I verified the data using the "Data Analysis" button in the Data tab, and by using a large number of if() tests to manually count. These latter methods arrive at the same answer. The histogram from the "Analyze Data" button inflated the counts for the smallest class.
