Loft not working for Add Solid, but works for New Solid?

Hello,

I'm having some issues with a Loft feature. If I select New Solid (creating a new part) then the Loft works as I would expect. But, I don't want two parts, I want a single part. However, when I select Add Solid (adding the geometry to the existing part) then the Loft fails. Why is this? How do I fix it?

Link to my part is here

    Because it's very likely that the surface that you think is coincident and shared between the two parts is actually slightly wobbling in and out of the part creating places where the two parts are intersecting at a line or point. Onshape's geometry kernel can't handle that. Just make the loft profile overlap with the first part slightly (link to my fix):
