Not showing all posts for selected category

Hello,

first of all congrats for your plugin, fantastic! Secondly I hope I have searched thoroughly for my problem.

Anyway, the one and only problem I have is when I select a specific category from the drop down menu it is NOT showing ALL posts in that specific category.

In all different plugins I have tried this was not a problem. Any help welcome.

Regards
