Crimson Vow’s Masterpiece Olivia Voldaren is not a Legendary creature and it should be.
As you can see on the link, the paper version IS a legendary creature.
If you decide to fix this could you also please take a look at Liesa from MID, she is only white in MTGPQ but in paper she is Black and white, earlier post here for reference @Oktagon_Support
