PowerShell Module for Dell EMC Unity 1.1 doesn't work with Unity OE 5.3.1

Some cmdlets in PowerShell Module for Dell EMC Unity 1.1

don't work with Unity OE 5.3.1.

Can I ask for help here?

I would like to write here more about the details but it keeps saying 'Something went wrong' so I'm making this as shortest as possible.

Thank you!
