Yes, it's `gnus-newsrc-alist' that will contain group definitions,
including seven (it looks like) for your archive groups, each one with
an identical method definition looking like:

(nnfolder "archive"
	  (nnfolder-directory "~/Mail/archive")
	  (nnfolder-active-file "~/Mail/archive/active")
	  (nnfolder-get-new-mail nil)
	  (nnfolder-inhibit-expiry t))

I know the file is a bit eye-watering to look at, but try to confirm
that you have seven archive groups in there, and each one ends with the
form above.

It's pretty weird that you're seeing this with your archive server,
because that one gets special treatment. Take a close look at the file
first, and maybe we can try something else.
