So, I can only assume this detail might've just slipped people's minds or they just went with it. But, this mod also translated several armor shop squad templates into armour including more importantly the interior and exterior leading to them disappearing from all referenced towns. I assume the OG mod was using them and instead of seeing that armor is english, it must've been using english english and slapped that u in there.

To think it was a translation mod that had me looking around for so long. Good work btw.

TBF, it's not like there're tons of people using the mod and likely they used it with the intention of engaging with only the modded content.

EDIT: I forgot the name but the armor shop template for big horn and other cities also needs to revert either its exterior or interior from armour to armor
