Minecraft translation convention does not capitalize prepositions such as "of" and "with". Your Registrate name generation is capitalizing these words. Some examples in en_us:
"Plate Of Fiery Snakes" should be "Plate of Fiery Snakes"
"Glow Venison Rib With Pasta" should be "Glow Venison Rib with Pasta"

Seems like Registrate is not smart enough. I will fix it
