Ele Custom Skin don’t filter post by categories when your are not logged

Hi! I have an issue with Ele Custom Skin Pro, the plugins works fine when you are loged on the website on pages that have post. But when you are logged out, the first posts that show are ok, but when click on the “load more” button, displays post from any category. This not happen when you use the post widget with Ele Custom Skin deactivated. Anyone with the same problem? I have read some similar problems with this plugins, but can’t find any solution.
