Please, find attached a sample test application, which we have created in order to simulate a scenario similar to yours. We haven't been able to reproduce the issue you've encountered, perhaps we are missing some of the details of your scenario. Could you, please, have a look at the application and if the problem persists, it would be very helpful for us if you're able to modify it, so that the issue is reproducible and send it back ( in a support ticket ) for our developers to investigate and debug locally.
