Go>Previous/Next Instance Menu option not allowed for replic

Why is it that even though I have a single instance of a replicant highlighted in DT (which I can confirm is a replicant because it says so in the info window, and because the document appears with red text) I am unable to choose neither the “Previous Instance”, nor the “Next Instance” menu options from the Go Menu?

Any suggestions would be greatly appreciated… Thanks!
