Hi Shachar,
I am not sure of what be might be causing this strange behavior without a working sample. I have tested this issue in the attached sample with Essentail studio V.4.x. I was not able to reproduce the issue. Maybe I am not following the steps that you are doing. Please post us a sample showing this problem or modify the attached samples to reproduce the problem, which will help me to find the issue and resolve this.
