If you submitted any primary applications, that's "previously applied." Same deal with Vandy, if you submitted a primary, that's "previously applied to Vandy."
If you sent your AMCAS to that school than you applied to that school. It doesn't matter if they sent you a secondary or not.
For Ooglan, you probably should call the admissions offices to which you applied and tell them of the misunderstanding. You don't want them to think you are hiding something from them. Good Luck.
