xargs: possible bug(s)

[Phil Fisher 02]

The following output was obtained as shown.  this does not seem to be in
accord
with the man pages.
If not bug, would appreciate response saying why not.

$ xargs --version
GNU xargs version 4.1.20

$ xargs --help
Usage: xargs [-0prtx] [-E eof-str] [-e[eof-str]] [-I replace-str]
       [-i[replace-str]] [-L max-lines] [-l[max-lines]] [-n max-args]
       [-s max-chars] [-P max-procs] [--null] [--eof[=eof-str]]
       [--replace[=replace-str]] [--max-lines[=max-lines]]

$ files="a b c d e f g h i j"
$ print - $files | xargs -I {} -n 6 echo {}
xargs: invalid option -- I

[--max-procs=max-procs]
       [--max-args=max-args] [--no-run-if-empty] [--version] [--help]
       [command [initial-arguments]]

$ print - $files | xargs -i{} -n 6 echo
a b c d e f
g h i j
$ print - $files | xargs -i{} -n 6 echo {}
{} a b c d e f
{} g h i j

Expected output:
a b c d e f
g h i j

Thanks
