For the life of me i cannot get this fillet to insert properly. It is a .015 R. I have tried all fillet options , all result as this. I also have been trying surfaces. If i offset the two surfaces at 0 then fillet the surface it seems to work. 

Unfortunately i have failed to convert this into a solid that will merge to my part. I have tried converting the surface edges on a 3d sketch on both sides to attempt to loft it together but it isnt working for me. Maybe i am approaching this all wrong , no idea. Need some suggestions please.
