Hello Martin,

Thanks for the screenshots. I made a lot of tests, but I`m not able to reproduce your issue. Please provide us steps or sample that reproduce this issue. It is very difficult to find the reasons for this behavior without exact steps or sample.

Let me know if you have any questions.

Regards
