Missing objects

Hello,

this article (https://blogs.windows.com/windowsexperience/2018/08/14/announcing-windows-admin-center-preview-1808/) as well as this video (https://www.youtube.com/watch?v=5kaUiW3qo30&feature=youtu.be) both discuss/show features that are missing in my deployments of Windows Admin Center.

For example: in the hyperconverged cluster manager the video shows write and read cache hit graphs. The article I mentioned above shows these as included in the 1808 version. Another example is in the video the presenter is able to select the timeframe of graphs.

Both of these are missing in my deployments (one 1808 and one 1903 GW install). Is this only available in the "workstation" version, or is there something I need to turn on or enable?

Thx in advance - M.
