I'm using the plug-in on multiple pages that are designed around categories for their posts. So, I exclude all categories except the one that is needed for that page. However, when months expand in which there are multiple posts in more than one category, the menu IS excluding the other categories ... BUT ...
It is showing blank spaces with the horizontal lines still in place. And the permalink is still in place and can be clicked to go to that different category's post. It's merely hidden the post titles.
I assume this is not expected behavior. I'm hoping it is just some setting I have set improperly or something easily corrected.
