Open the hub what you want to change --> Left top you have options gray buttons (edit, stats & delete)
Select "edit" --> then you will take to edit page --> then you can see hub settings
You can change "Title", "Category", "Ads"
You can change "Title" in that capsule, then go down & select "done editing" to save your changes. I think this would help you to solve the problem. If you need any more help let me know. Im always happy to help you.
