A recent update in Sitecatalyst must have changed the way that this works, making trended reports difficult to use now. For example, run the Pages report, bring in "Bounce Rate" metric first, then the "Entries" metric, sort by "Entries", and then change to trended view. The pages with most entries are no longer the top ones shown. It re-sorts by "Bounce Rate" and shows pages which are not top viewed pages. On a report like this you would usually want to look at the trend of bounce rate for top pages. The only way to do it now is manually select the pages that you want which is time consuming and shouldn't be necessary.
