The this is at least _very_ unusual and AFAIK the first time someone has reported this to this list. My personal tests support what carl eugen and countless other competent people have said on this list. So either you go to the trouble of building a reproducible test case that you can share without an NDA or you are probably on your own and you should at least stop being rude to people who to the best of their (undisputed) knowledge are trying to help you with a patience I don't think anyone could ask them to have. You are a beginner and it's fine to ask questions but you attitude is like pissing on the table of the family who has just invited you for a free lunch and then insulting the cook without ever having cooked yourself in your entire life.
