Loft leaves open hole

 From:  nycL45
I have used splines to make the bowl of a cooking spoon. When I loft it, there is small open hole where the last spline is located. How do I close that hole? When I extrude the bowl, the hole remains.

I have played with different Loft Styles and Profile combinations. And, I have tried checking/unchecking the "Closed" box. BTW, when I tried a search here, there were 515 returns.
