How can I copy/mirror elements/components, without the copied entities being connected to some kind of non-existing geometry?

Hello, I am currently meshing an assembly, consisted of many identical parts. So I made one part, which I now need to mirror/translate etc. At the same time, I need to keep the elements within the same (original components) - thus I must use the mirror/transformation tool to elements, as Hypermesh doesn't support duplicating components, while also keeping their original identity. And when I use the mirror or translate function, most of duplicated elements are attached to some kind of geometry, which is not present there originally, but as not all of them are attached, the mesh is simply "broken" - I cannot connect/stitch the split elements, I cannot disassociate the elements from geometry in any way... I tried to change every possible HM settings, that could be connected to this functions, but the result is always the same.

The only possible solution, how I can create a "functional" mesh without some strange geometry associations, is to duplicate the components, but then I have the new elements associated to new components, and although these have the right (original) properties, I still need them to be under the original components, and this can be done only by manually reorganizing the elements - doing at least 24 times, when every part has 14 components, would be pretty painful... Can someone help me in any way?

In the attachment there are 2 pictures - the first one from the original mesh, second one is the copied "broken" mesh - you can see one of the strange locations marked with green colour. There are also visible some ordered nodes, which are not present in the original mesh.

    Hi
    In 2022.3 this can be controlled in another way then in in 2022.2
    under preferences/meshing/advance you now will be able to choose (and not creating geometry is default)
    So I hope your related issues can be resolved by using 2022.3
