In order to get the best help possible, you may want to post and image of your issue or share the .SKP file.
Best guess is that your arcs are not in plane with the straight lines. I would double-click the face that worked, right click and make a group, then use Move to maker a copy, rotate, and place it on the other corners.
This is a good example of why we ask for the model. Seeing just the image, we can only speculate that the most likely reason is that the points are not coplanar but with the model we could tell you for certain!
