The report subscription provides wrong results. The "current selection" shows inconsistencies. Why?

This may occur because many number of reports might have been scheduled to run at the same time (for example, 15 reports scheduled to run at 8:30 AM on every Monday.). This may result in a faiure in executing individual jobs simultaneously. Set some among the reports at different time, with the time intervals of 3-4 minutes between each report subscription.
