Bevel forms Triangle edges instead of Round Curve

MasterWorks

I have been trying to find out why the bevel feature and modifier keeps making triangle vertices instead of round curves. The top Pic is the goal, but without rounding the entire edge loop.

Looks like you're only beveling one edge, rather than the entire loop.

If this is your intention and you just don't want the triangles to appear as faceted, you'll probably want to Right-click on the model (object mode) and choose Shade Smooth, and then either adjust the Object Data Properties: Normals: Auto Smooth Angle, and/or possibly select some edges to manually mark as sharp edges.

So I am trying to get a bevel just that edge so that I may extrude it and form a curved surface on the top of the polygon, but a flat surface on the bottom.

Note to get this working I had to bevel the entire top part first.
