Our nodebb has a phantom category that seems to appear at the bottom of all our categories. When inspecting, it has no CID but shows up in each theme. This is from our API view of categories for the category:

{"parentCid":0,"name":"","icon":"hidden","unread-class":"unread","children":[],"totalPostCount":0,"totalTopicCount":0,"posts":[]}],"title":"[[pages:categories]]","breadcrumbs":[{"text":"[[global:home]]","url":"/"},{"text":"[[pages:categories]]"}],"loggedIn":false,"relative_path":"","template":{"name":"categories","categories":true},"bodyClass":"page-categories"}

Any help will be much appreciated!
