I understand the “R” part but adding the “R” to the end of the original number is how they normally do it. God Mars was GX-40 and the renewal version was GX-40R. In this case, the original was GX-33 and now we have GX-83R. Edit: Lol, never mind. I just zoomed in on the magazine image and it is GX-33R. @Gabriel Contreras just made a typo. Haha.
