How do I hide my internal mailing lists from the topics page?

Hi, 
I would like my clients to select which type of emails they want to receive from me. I have newsletters, webinars and events and product notifications. 
I set up topic management with these three topics but when I go to the management page, it also shows a list of all of my internal lists, including test lists etc.

Here is a link to my page: https://campaigns.zoho.com/campaigns/org642404591/topics.do?actionMethod=showTopicConfigView&mode=topicPrefPreview

Is there a way to hide all the "other" lists from this page?
