There seems to be a lot of confusion about PowerShell problem reporting.
The difference between Windows PowerShell (the one you find pre-installed on Windows machines) current version v5.1 and PowerShell (the open source project) current version v6.0 isn’t really understood and that lies at the heart of the problem.

If you have a problem with PowerShell and you want to report a bug or request a change or new feature the place to do it is here – https://github.com/PowerShell/PowerShell/issues
The two flavours of PowerShell should be regarded as completely different technologies and treated accordingly.
