problem when extruding a 3d sketch on a curvy surface

so i need to make a handle just like one in a picture, and im kinda close to completing it but when i try to extrude leaves they gets messed up in a strange form (example in screenshot). so whats the problem?

Problem is that the extrude from the 35 sketch does not know which way to extrude. Have a look at the file attached.

I extruded the petal from a 2D sketch, then did a surface offset, and cut away the part I did not want.

(Keeping thing symmetrical helps!)
