Confirmed!, same ,form file and after installing PreForm version 2.12.3 (downloaded from other post for older versions)  
[http://forum.formlabs.com/t/preform-older-versions/9686](http://forum.formlabs.com/t/preform-older-versions/9686)  
and removing and adding the same point in order to recalculate the supports algorithm, it does not happen.

Please, doublecheck this possible bug.

Best regards,  
Enrique
