The modifiers were using price levels that were driven by the shift levels of the menu item they are attached to. There is also a Timed Event assigned to the shift level for the menu item as well which is causing M$ to look for the actual price associated with the mods which was set to $0.00. I added the prices for the price level that matched the mods based on the shift level assigned to the menu item and it worked after that.
Charge for modifiers are dropping off during Timed Event when modifiers are changed
