Two passports

I have two passports (one 2TB, the other 4TB). Both can be seen in “computer” but I can’t see both to check on backup status and it keeps asking me to re-setup criteria for backup. When I had one, there was a place to recall what was backed up and when the last one was done. No longer because when I shift to the second (if it even shows up), it’s asking me to re-setup, “Signatures” are not the same (two different size Passports) and I’ve been through all the things I can google, none of which work. I just want to be sure both are backing up what they’re supposed to and be able to easily check that. Thanks.
