Answer
It's a known UI limitations for Windows Server task manager, WMI, or PowerShell queries to pull CPU information, as per Microsoft Support KB:

Task Manager does not display L2 and L3 cache sizes, or displays incorrect L2 and L3 cache sizes

Task Manager displays an incorrect number of sockets

For example, for a single-CPU one-socket system, Task Manager displays two sockets. For a two-socket system, Task Manager displays four sockets.

Task manager displays an incorrect number of Numa nodes

For example, for a one-socket system, Task Manager displays two Numa nodes. For a two-socket system, Task Manager displays four Numa nodes.
