Saved in draft but later its not showing

Form is developed in age section i have put parameter no less then 18 years. But in ODK App after i save the form after filling up the form in ODK Draft then if i look into the draft then it shows blank in age section.

Hi @Joydeep_Sarma1

The problem is that that answer disappears after saving a form. Am I right?
Could you tell us what version of ODK Collect you are using?
It would also be helpful if you could attach your form here.
