Reporting -> Disk I/O - Disk no display

Hi all,

I noticed the reporting → disk of my TrueNAS not displaying result, other like CPU, Memory, Network, System don’t have.

May I know how to fix it? Fyi, I am running the TrueNAS as a VM with virtual disk. Previously was on 25.10.0.1 also having this issue and just upgraded to 12.10.1.

Thank you
