Why did Smallfoot get no Oscar Nomination

The Reason for Warner Animation Group's Smallfoot ending it's Oscar Nomination Proposal at the 2019 Oscar Nomination announcements is that DreamWorks Animation SKG's The Boss Baby lost Best Animated Feature to Disney Pictures Entertainment/Pixar Animation Studios' Coco at the 2018 Oscars.

STX Entertainment announced that it's first animated film UglyDolls will have to get an Oscar Nomination Next Year.
