Hello Shachaf,
Thank you for writing.
I tried to reproduce the problem locally but everything is working as expected on my end. There is sample demo project attached which I have used in my tests. Could you please take a look at it and modify it on a way to replicate this undesired behavior. This will allow me to investigate it and provide you with further support.
I am looking forward to your reply.
All the best,
Anton
