guix-edit shows "Autodoc not available..." w/ 2 REPLs

[myglc2]

Running guix/debian ...

When I do 'M-x guix-edit RET screen RET' I get ...

"Autodoc not available (No Geiser REPL for this buffer (try M-x run-geiser))"

... This puzzles me because guix already has 2 REPLs running ...

 *  * Guile REPL *          1228 REPL             (Guile REPL<1> run)
 *  *Guix REPL*              312 REPL             (Guile REPL run)

So... I wonder, should I really need to start up another REPL?

Or...  is something fishy with my setup?

My .emacs.d/init.el file contains ...

***
