You're experiencing the change to the (not so) new guix pull. Now a complete guix is installed in ~/.config/guix/current. The guix installed in your profile doesn't look for packages in that directory, but uses its own definitions. This has a side-effect: whenever you try to update your profile, not only does your guix not use the newer guix, but the only guix package it knows of is a least 1 commit *before* your current guix, hence downgrading guix (and package definitions) at every update. Make sure you uninstall guix from your profile and add ~/.config/guix/current/bin to your PATH. Then you should be able to use the freshly pulled guix.
