Confusion about card existence

I put "state" in the "Go to card" and got an offer to create a new card. I wanted to make it a Cardtype, and when i clicked Create, got:

Problem with card State:
Confirmation required State has 4 dependents

So i created it just as a Basic card (which worked). Then i tried to delete it (i was going to create it in a demo), and got warned of several +state cards (eg John Abbe+state). But if they were there, shouldn't i have seen a state card in the first place when i put it in the Go to card box...?
