Posts mapping to categories not working properly

I am using autoblog to import posts into certain categories which are then displayed on their individual category page i.e one page per category such as those below.

http://portal.mindsharehr.com/hr_analytics/
http://portal.mindsharehr.com/hr-social-media/

I just noticed that sometimes the category pages show the correct posts but most often show the same posts across all category pages! I am not sure when this got messed up though the last thing I did was upgrade my WP Sahifa theme.

I dont have a backup so can't restore either. Can somebody login to the website and help me figure what the problem is (support access enabled).

Thanks
