Duplicate domain bookmarks in Domino Administrator

I get duplicate domain bookmarks in Domino Administrator when refreshing server list.The only way to remove I found is to remove bookmark.nsf

Is this a bug? or Is there something misconfigured?

Is there a way to remove these bookmarks?

Thanks.

Getting this behaviour in R7 admin client. Looks like a regression. Every time you go to refresh server list, it creates a new domain bookmark
