Exploring your file it appears that giving center points more simple coordinates (only integer) allows your definition to create valid spheres. See the picture below.

It doesn’t give you the reason of having invalid surfaces but may give some point to investigate on…

Hi BaptisteC
Thanks for your reply

Further examination shows this:

Definitely a bug of some sort, it should not be possible to create an invalid sphere from valid points and radii.
