Ring cameras show under separate locations

I recently added an interior camera to my Ring set up - I only have the doorbell and that interior camera so far but plan to add window sensors etc. So when I added the interior camera it set up a second location (same addres etc) so in order to look at both cameras simultaneously I have to select “all cameras” or something like that. That’s ok but I want to upgrade to basic plus but when I do that the upgrade only sees my doorbell and not the interior came. So, question is, how do I get both cameras (and any future cameras) on the same location ? Is this somehow linked to whose Amazon account set them up (maybe my wife and I did them between us ?) Thanks to anyone that can explain or hel me fix this.
