Yeah, stupid question, I know. So I'm in Ranks Management page of the FB CP. I want to delete all of the default ranks so I can start fresh and put mine in. I select them all in the checkbox, hit delete at the top, and a bar pops up on the new page saying "Rank Deleted". Nothing was deleted or changed. I did it with individual ranks, ranks that aren't occupied by users, I tried it every which way.

I'm positive there's some obvious solution, just present it to me without too much flaming. Thanks.
