Boolean union modifier doesn't look right I have a boolean modifier attached to the circle set to union with the curve object. I'm unsure why there is a strange line where the two shapes overlap even when the curve object is hidden from the viewport. I've recalculated the normals to face outwards on both meshes and I've checked if there are any overlapping faces and i'm pretty sure there aren't any.
Please help, thank you.
I tried to fix:

I set the Overlap Threshold of the boolean to 0.
I moved the bottom face of the Curve.001 down by -0.0001 mm
