Did the 'get leftovers' option disappear or something?

There is no Open option on my CC fridge, the one with the orange symbol.
I have a lot of food mods and deleted some menu expanders, so I'm working on it and need ideas to help me fix it.

Did you try this in a different household? Sometimes it also helps to travel or switch houses just to reset stuff. You could also try to delete all food in fridge, and cook a new meal to put in there, to see if it works with something fresher. "get leftovers" works in my game.
