How can I modify this category list?
I want to add AAE, Sega Model 3 and Daphne to the 'Arcade' category so they show up as 'sub-folders' within the Arcade 'tree'.
Right now, AAE, Sega Model 3, and Daphne are showing up in the Parent category list under Platform Categories, all of which I think should be categorized under 'Arcade' (see attached).
Any suggestions?
