Hi,
Don't worry about the issue.
I checked on your site. Popular Posts in once month work fine.
Logic of "Popular Posts in once month". when you choose order by Popular Posts in once month.The block will display the article that is known to be viewed a lot during the month. http://prntscr.com/nle4q2
Please check it again.
Best Regards,
