Help on fan speeds display in Dashboard

SYSTEM INFORMATION
OS type and version Ubuntu Linux 24.04.4

Authentic theme version 26.22

Hi, I see Webmin is capable of displaying fan speeds and interesting in troubleshooting a situation where I see the CPU Fan Speed but not Chassis Fans.
Output of sensors (and sensors -u) show the info and I can change naming conventions if needed (i.e. .conf file controlling the output of what we see) - extract below for reference where I’ve been playing with some of the naming already.
Is there a naming convention I need to use of webmin is expecting to see?
Apologies if this question has been asked before and if it has please point me to where I can find info to help me troubleshoot.
