On my blog I have 5 categories at the top of the page. However, there is an empty space between the 1st and 3rd category in which the title of the second category will not appear. You can actually click on the empty space and it still takes you to that category. The word just does not appear. I have tried updating it several times and nothing is happening.

In order for Categories pages to have data to be displayed we have to publish posts with the Categories assigned to them. Until we have published a post in each Category there is nothing that can be displayed.
