Some cards are not in the database,
such as:
Title: Vampire's Vengeance
Cast Type: 2 Any 1 Red
Type: Instant
Rarity: Uncommon
Series: Crimson Vow
#: 180/277

Can anyone help?

It's in the database.

Looks like there's a bug in card search. Until it's fixed, you can go to the Crimson Vow edition page and add cards from there.

thank you very much

Yeah this is confusing. It's actually not a bug, but it's spelled differently: "Vampires' Vengeance" not "Vampire's Vengeance".
