When searching for Clement of Rome, if one selects the entry (red box) it produces a search argument with an unknown data type see lower left. The actual Factbook entry uses both Clement of Rome and Pope Clement I to refer to the person … but not the title used by the search. This sort of error is very annoying when one it trying to identify the alternative names one must use to fully search one's library (excluding the issue of multiple languages).
