    Hello Eric,

     

    Thank you for your post!

     

    I have been looking into it and have created a small sample application in order to test the functionality, that you have reported.

    Using the mentioned sample application I was not able to reproduce the issue. Would you please modify it with the functionality you are using, so it shows the issue?

    This way I would be able to further investigate this matter for you and provide you with further information.

     

    Thank you for the cooperation. Looking forward to hearing from you.
