Sorting bug in Power BI Service - different result than in desktop version

Anonymous  thank you for your tips.

This morning I found some time for the following testing:

Found some interesting staff when publishing the report to an old workspace:
After publishing and app update, I get two reports in the workspace:

The faulty red marked one is included in the app.
The green marked one works absolulty fine and is not included in the app because the app is stil faulty.

Very strange that the "include in App" shows the status in the opposite way. --> There is something wrong!

When I publish the report to a completley new workspace, everything works fine. --> Work around!

In my case, the app is embeded in another software. Change to a new workspace would mean that I have to change the link to the app in a live system with several hundrets of users worldwide. Will do it now.
Hope I could give MS a hint to solve the issue and the community a possible work around.
Have a great day!
