Case properties disappearing after submission of follow-up form


I have successfully bulk uploaded cases to commcare, mapped case properties, and pulled them into the survey using hidden values. I have selected the properties for display in the case list, case detail, and throughout the survey. An issue occurs when I select a case and submit a form; when I go back into the case to submit the form again, the case properties are blank in the case list, details, and survey. The case itself does not disappear, just the properties.

Thanks for your help.

Resolved. When I added the uploaded case properties to blank hidden values to pull them into the application, I also needed to add the case property as the default value in the logic of the hidden value so that the case property wasn't being overwritten as blank.
