Hi Priya,

I am afraid that the provided information is not enough to determine what have caused the unexpected behavior. At this point in order to find a quick solution/ fix of this problem it will be best if you open a formal support ticket and send us a simple running project (incl. DB backup if needed and so on) demonstrating the problem (and step-by-step instructions on doing so). In that way we can reproduce and pinpoint the problem you're facing on our side, understand the logic of your application and provide a solution.
