Whichever ruler I start as, there's a legend seed listed that has this same broken loc. The name of the legend is somewhat randomized. I loaded up CK3 without mods and was not able to find this legend seed on any of the rulers, even the ones who don't have their own specific legend seed. So I believe that the existence of this seed everywhere is a bug, and then its localization being broken is a secondary bug.
