Server listed twice in gnus-group-enter-server-mode

[Richmond]

I have ended up with the same server listed twice in
(gnus-group-enter-server-mode). I think this may be because I originally
added the server using (gnus-group-browse-foreign-server METHOD), and
then added it to .gnus as a (gnus-secondary-select-methods) and then
later or maybe at the same time added tls with port 563. So now I am not
sure how to delete one, preferably the one using 119 if indeed there are
two occurences. When I use the letter k to delete the server it tells me
I must delete it from the configuration file, but there is only one in
.gnus, where is the other?
