I mean the normal antiscia modul: extra-antiscia.
As an alternative, I then used extra-mirror classic and there the horoscope chart was correct.
Extra-declination-anticia is something special.
I use antiscia in every horoscope, so I once wished that antiscia and contra-antiscia could be included in the aspects.
In Germany we call them "Spiegelpunkte" and use them like main aspects. I find them highly effective.
