Whenever your model required more than regular repair to get the model waterthight, it requires a so-called 'advanced repair'.
Our repair algorithm is trying to fill bigger gaps, connecting more distant triangle points and other more inventive ways to make the model quotable. 
As the repairing methods might have altered the geometry of your model, it is advised to inspect the repaired model in the 3D viewer. The 3D viewer can be opened by clicking on the image in the configuration screen. 

Typical items to inspect are: holes that are filled that should stay open, unwanted extra areas, removed areas.
