Help a outline appears on my 3d object

[Adilayhm]

Hello, i'm new working with the 3d tool on illustrator and I've encountered a problem, I want to make a circle figure but it has something like a outline, first I thought I was only in the preview but I exported the image and was still there.

 this is how it shows in the program

this is the exported file

Can you improve it when you change the render settings (top right of the 3D and Materials panel)?
