Late fix, but also specific to this mod: going into camp, and exporting the character...then you can change the name (in the file, not the filename) to whatever you like, then import it back in. As long as the filename matches what's expected, you'll change their name.
If anything, it wouldn't hurt to just correct the speling to "Palatinus", if that's what is intended... I have no earthly idea what Palantinus is supposed to mean, either.
