Field data not present until Update clicked

Good morning

I created a new field and used the type AUS since i am using this to look up employees, once you select the employee and save you will notice the selected user code is present. 

The problem is when you go back into the function and see the data it is blank, however once you select update on the far right the data will appear. 

Does anyone know how or why this might be happening? I attached a photo of before you select update, and then after.
