The Hubs that appear on your Profile Page are featured Hubs only by default. To display all Hubs enter the 'Edit Profile' queue → Skim to 'Show only Featured Hubs on my profile:' → Select Yes or No.
Footnote: Above that option is where you can 'Spotlight' up to five Hubs. When chosen they appear at the top of displayed hubs. They will roll from one to another while viewing.
