    Thank you for reporting this. I was able to replicate the issue with the cloned form. Let me forward the issue to our back end team to take a look. You'll be posted through the thread once there is an update on this.

    Thank you for your patience.

    Hi Kiran,

    I randomly deleted fields and could, occasionally, get the thing to work. So I think it is a server CPU or memory resource issue.
