Hi @lokesh-garggreenhonchos-com
The validated field addon is not part of ACF and is developed by a different author. I would suggest you post in his support forum instead 🙂 He seems to resolve most of the issues brought up there as well: https://wordpress.org/support/plugin/validated-field-for-acf
It would probably be a good idea to check your console log in Chrome dev tools too for errors to post in your support-ticket there. I’m guessing you got some JS errors.
Good luck!
