gopass clone deletes previously added pubkey

[tatome]

I've set up a git repository, and initialized it as a store for gopass on my home machine.

Then, at work, I created a dedicated gpg key, ran gopass setup and then gopass clone git@some-gitlab/some-repo.git work/some-name.

This creates a new commit in the local repo that deletes the one public key in .public-keys and adds two more (one matching the e-mail address I gave when running gopass setup and the one I chose when running gopass clone.
Instead, I was expecting it to just add the key I chose when I ran gopass clone.

I'm probably just holding it wrong™ but I can't find any hints on how to hold it right in the docs or tutorials; they seem to imply that gopass clone with a sub store name should just work.

I'm using the gopass version that's currently in the Arch Linux repositories: gopass 1.15.3 go1.19.5 linux amd64
