tsFillHole Command

Using a previous version of Rhino and Tsplines I was able to create a smooth transition when using the tsFillHole Command, but now it just flattens the top. I would like to be able to get the results I used to get if anyone can help please. (See Images attached)

The new version tries to keep creases as much as possible so doesn’t smooth out the top part.
Try, instead, to extrude the edge to a central point and weld the resulting vertices.

You should be able to right click on the crease command as well for TSPlines. And click on the top edge, it should change to being a round smoothed cap. I know once I switched to the new version, and started extruding some things everything extruded as creased for me instead of being it’s normal bubbly self.
