This works correctly on our cluster:

$  sreport -t percent -T ALL cluster utilization
--------------------------------------------------------------------------------
Cluster Utilization 2021-05-13T00:00:00 - 2021-05-13T23:59:59
Usage reported in Percentage of Total
--------------------------------------------------------------------------------

Referring to https://slurm.schedmd.com/tres.html, which TRES are defined 
on your cluster?

$ sacctmgr show tres

I get this output:

     Type            Name     ID
-------- --------------- ------
      cpu                      1
      mem                      2
   energy                      3
     node                      4
  billing                      5
       fs            disk      6
     vmem                      7
    pages                      8
