Dependent list not working without authentication - Radsystesm Classic 4.6.1

I have login authentication and registration , and roles and permissions in my project.
My Expertise/Add page have two field one is Expertise and 2nd is Skill, when I login and select expertise then Skill is load related data and working fine.
But in “Register Page”, I have added “Expertise/Add” page as subform. And “Register Page” is without authentication. When run the project and load the “Register Page”, Dependent list is not working in Expertise/Add page and when i select Expertise field then Skill is not loading related data while it same page is working fine after login.
Have any solution?

please note that the video shared does not include the details I asked of you. Please show me the details displayed on the command prompt, when you try using the dependent field on the generated app. I would prefer a screenshot as the video shared was not clear enough to see any text.
