Package Installed on NAS Drive are not appearing in the Add-ons list Dynamo 2.12

I am setting up a new computer with Revit 2022.1, Dynamo 2.12

Using Dynamo > Preferences > Package Manager > Node and Package Path
I have added a new path and set this as the default

I installed two packages, these are now in that file location.

The package Manager Tab shows these are installed, but they are not appearing in the Add Ons List

There are a number of posts on this message board indicating that I can locate packages on a NAS drive. Have I missed something?.
