Tap the ⌄ button to left of the meal name to show hidden foods.
You can hide the foods logged in a meal on your daily log. When foods are hidden only the name of the meal and its total macros remain displayed. Some people, especially those who log days in advance, use hiding foods as a way to identify which meals they've already eaten and which are left to eat.
