Just to be sure, did you change the EOS R file naming scheme to match the 60D? That's where Canon has listed known issues like this. Theoretically, and I use that term loosely, if each camera had it's own unique file name/numbering, switching the card between the two shouldn't cause that issue. But like Paul said, the EOS ecosystem has a bad habit of picking up the number from the .cfg file (I think that's the one).
I believe Occam provides guidance that 'DSC' is the standard default name for digital cameras being a
amera .... And hence, a new camera to the original concern of the OP.
