I had such problems with the romani too. For some reason the internal naming does not always work with the romans. For me it works with Captains but not Admirals and not FMs. The game seems not to use the A-K internal names only the one without an extra letter. E.g. one Lvcivs is influenced by the console commands but none of the other Lvcivs, if the first one dies one of the other can be used with the console commands.
