Modifier Sort Order vs Modifier Order Priority

What is the difference between Modifier Sort Order and Modifier Order Priority?

Modifier Order Priority determines the order in which your modifier groups are displayed during the ordering process on your Toast POS and the order modifier groups appear on kitchen tickets when there is no sort order. 

Modifier Sort Order determines the order in which your modifiers are displayed on your printed or digital kitchen tickets to allow your kitchen staff to easily read and prepare orders.

Kitchen tickets sort modifiers first by Sort Order, then by Modifier Order Priority and then by the order in which the modifier is entered.
