Bob's response was the correct response.

Since the libero must be designated on the teams lineup for the set, a player cannot switch from being a player on the lineup to a libero during the match.

Sure they can. They just can't do it in the same set, unless it's a libero redesignation, and even then, an initial libero would have had to have been listed.
