If you want to remove or delete a section from your page, just follow these easy steps:
First, hover over "Edit" under your biography information (next to "Upload") and click "Add, Remove, or Rearrange Papers & Sections."
Then, move all items out of the section you want to delete. Once your section has no papers in it, the small triangle to open the section will turn into a little trash can.
Then click save! Your section should now be deleted.
