To display the "favourite wikis" part in your profile you have to first make an edit on these wikis. To edit your profile, go to your userpage, hover over the profile header and click on the "Edit" button in the top right corner. On the bottom of it, you can remove wikis from your favourite wikis that you don't want to be displaying there. There's a maximum of four wikis that can be displayed in your favourite wikis.

You can read more about editing your profile on Help:Profiles. What other aspects of your account information did you want to edit?
