This is the relevant part. I think the rest is noise caused by the issue in the manual being copied to all translations:

./doc/guix.texi:29670: warning: node next `Network File System' in menu `Continuous Integration' and in sectioning `Samba Services' differ
./doc/guix.texi:16349: node `Services' lacks menu item for `Samba Services' despite being its Up target
./doc/guix.texi:29985: warning: node prev `Continuous Integration' in menu `Network File System' and in sectioning `Samba Services' differ

In particular, it sounds like you didn't add the Samba Services node to the menu near line 16349 (that's a different menu from the one at the top of the file I believe). The other warnings should disappear after you add it.
