Anatomical Elements and tooth gaps

I observed something strange you can reproduce with most likely each Genesis Figure:
Do the following steps: Load a new figure, apply a skin, open it's mouth, change to the geometry editor, select a part of one tooth, select then all connected (one tooth is selected), hide the selected polygons and delete then the hidden ones. Then you have finally a figure with a tooth gap.
But: If you do the same steps with a figure which has already loaded a genitalia, all looks fine as long as the Geometry Editor is the selected tool. If you change back to the universal tool, the figure has holes.
An even harder example I found, as I equipped Girl 6 with the 'New Genitalia for V6'. What came out you see in picture 6, 6a had been rendered after I activated the 'Geometry Editor' again.

BTW.: The male is G8 Base Male. I tried to do this with Michael 8 first and each time I tried to delete the hidden polygons DAZ-Studio crashed
Please remove the skin from the figure, and crop the screenshots to show the gap without showing the actual genitals.
GeoGrafts (such as the anatomical elements) require exact vertex matching at the welding edge - if that fails they won't weld, and the Sub division will then open up a gap. I suspect that when you remove tooth mesh you are throwing the vertex numbering out. If you want to remove a tooth better optiosn would be to assign to a new surface and make that transparent, or create a new face group and assing that to a new bone, then make the bone invisible -either of those should eb safe with respect to vertex ordering and numbering.
