hi Johnny Black, you don’t need to buy visual composer. why you think you need to buy it?
we have already pack visual composer with the themes. you will just need to remove your old visual composer, and you will get newer version of visual composer.
i don’t understand your second question, may i know what the issues? i see you have 5 content, while what showing on backend is 9. if you don’t know how to alter number of content on page, you can go to wordpress admin panel > setting > general > reading.
