Trick or Treat Exchange

Hello, I couldn't figure out what disambiguating meant (googling the definition didn't help) and since all the characters I nominated were existing in AO3 I stupidly thought they were fine. It's just sunk in now when I saw two that some of my characters weren't in the tagset and I went to check my nominations form and saw that the only one of a group that had the show name in brackets was the one approved. Is it too late to get the others approved? I"m so sorry to bother you :(
