I am using version 4.7.24, I downloaded 4.7.32 and tried it there as well but I am getting the same result. No geometry is being add and when I switch tools it disappears. Not sure if I am doing something wrong at this point.

I am in the process of retopoing one of my meshes and I am needing to use the primitive tool in the retopo room. I create the primitive and fit it to my base mesh and then hit apply, multiple times following the exact process shown on the 3d coat youtube tutorials. When I switch to a different tool the primitive mesh disappears. I have watched multiple videos showing that once apply is hit the geometry is supposed to remain in the viewport, however, that is not what I am experiencing. I can't seem to find anything online as to why I am getting this problem and it happens with the both the primitive tool and the premade RtpModels on the right hand side of the interface.
