    Hello Vo,

    We're not currently aware of such an issue and without being able to reproduce it at my end it's hard for me to suggest a possible cause for it.

    May I kindly ask you to open a new support ticket (as our system only allows images being attached in the forums) and send over a small sample project where the exception is isolated so that I can further assist you? Thank you in advance for your cooperation on the matter.
