Questions Regarding Case List Display Properties - Case List Display Properties Are Not Displaying As They Should

In my application, in the E. Coli Test Results form, I set up display conditions such that the Name (name), Address (address), Gender (case_gender2), and Age (case_age2) appear on the case list. See the attached photo:

However, when I actually use the application, the only display conditions that are shown are name, gender, and age. Is there a reason why that is happening? See the attached photo:

Any input regarding this would be much appreciated! Thanks so much!
