Accounts Receivable Analysis Report

We use the AR Analysis Report frequently - the verbiage at the top gives a summary of the report, however where our Receivables show an increase of 2.9% over the last period, the summary at the top states that it is 'down' 2.9%.  The prior 'six period average' in the summary also states that it is down 14.9% when it is actually up.  Am I misunderstanding how this verbiage is stated or is this an issue with the report?  Thanks!
