xpk Cluster Queue resource group "cpu" resource quota incorrect for a CPU-only cluster

We have a CPU-only cluster -- n2-standard-32-1024 that has 1024 of n2-standard-32 nodes. There, we technically should have a rough 1024 * 32 CPU resources but I'm seeing 1024 nominated quota from `kubectl describe clusterqueue cluster-queue`:
