MAAS doesn't automatically refresh resources information for a VM host (except for updating used resources when machines get composed/removed from MAAS).
It's possible, though, to manually refresh the information, either from the UI (from the VM host dashboard) or the API (maas $profile vm-host refresh $id).
Doing so will refresh both VMs and cpu/storage/network information from the host.
Could you please try this and verify your changes are reflected?
