strange to me auto completion error

[Michael]

whenever I type rm $LFS/so <tab><tab> it is replaced with:

bmike1 at bmike1-desktop:~$ rm \$LFS/so (and the auto complete options)

which upon completion results in:

rm: cannot remove '$LFS/sources/wget-list': No such file or directory

why is it doing this?
