How do I get rid of an object's shadow cast

Hello Everyone,

So I am fairly new to this and I just finished my first animation for a show I am working on. But the space ship I animated is casting a weird shadow in the air. I want to disable it and when I disabled cast shadow it still showing. What am I missing? I included a snippet. Can anyone please help with an answer. Again I unchecked “Cast Shadow” on the fighter jet already.
