Weird, that definitely works for me.

Could you then see if this can be reproduced in a VM?  That is, run:

  guix system vm config.scm

where config.scm is your system config, with Emacs added to the
‘packages’ field, like so:

  (operating-system
    ;; …
    (packages (cons emacs %base-packages)))

If the problem doesn’t show up in the VM, it would mean there’s some
corrupt state somewhere on your system.

HTH,
Ludo’.
