You meant: The /unread/ messages are marked as read?  

Just to avoid confusion about the terminology: In IMAP there is a
distinction between Read/Unread and Seen/Unseen messages.  An Unseen
(or: Recent) message is a message that has not been seen by the IMAP
client.  As soon as the client "sees" a message (i.e. SELECT the
mailbox) it loses this flag.  Sounds like this is happening.  Seeing
the message does of course not affect the Read/Unread flag.

If it really is the Unread flag that is removed, it sounds like
problem of your setup or Gnus.  AFAIK just tells Gnus to open a
particular message in a particular folder.

WL works fine (as always).
