Intentional holes not printing

I have no clue whats wrong with my print, but no matter what I do it keeps coming out wrong!

 

So im trying to print out a simple hollow tube however when I slice the model it automatically fills it in. I have tried turning on and off multiple settings but none of it seems to give me my desired result. Can anyone spot any issues?

    It appears as though the model you used has issues. I downloaded it and had the same outcome,  I then opened it with 3D paint and saved it as a glb file and it seems to work OK?

    It seems that the model normals are throwing off Cura. The inner wall normals are reversed in relation to the outer wall normals.

    It was the model's normals that were broken! I fixed the normals and tried re-printing it and it all worked out. Thank you!
