Pad not Cutting Existing Toposurface

This issue comes up when you have multiple toposurfaces on multiple phases. Each phase has it's own 'hole' made with pads. Every other phase shows the pad cutting a hole in the toposurface except for the Existing phase. This happens when there are multiple toposurfaces occupying the same physical space but on different phases. The only workaround that I have found is to use the Split Surface tool, cut the shape of the hole (pad) and then delete it.
