Hi Xepoor,
It is very important to let Microsoft know your findings. This forum is good for airing the issues, but it is not a communications channel to the Microsoft Developer team.
Before proceeding, be sure your installation is current. The current update is 16.40
How to check your version of Office:
Go to the application menu. For example, in Microsoft Word, go to the Word menu. Then choose About Word. The resulting
dialog tells you which version you have.
Then, go to the application's Help menu. Choose the Feedback/Contact Support option. Using that method you send your feedback to the appropriate team for each application.
Thanks.
