On default Lovelace UI - a device's Power is displaying wrongly

I have a Vesternet VES-ZW-HLD-016 High Load Switch on Zwave JS.
In the default HA Lovelace Overview (and device deeper views) its showing the switch’s "Electric Consumption [KWh] as 5,515.300. But digging deeper, this value is what its “Display Precision” is set to, not the power used. “Display Precision” has a dropdown list of values, all variations on 5,515. Also, there is absolutely no way the attached device (shower fan) can have used anywhere near that KWh since the Zwave switch was installed a few months back.
Q1. How can I reset this HA device’s Power used readings? (Or view them to cross check the error’s source.)
Q2. Any ideas why I’m getting such a high/erroneous reading and how to correct it?
All the device’s parameter settings look ok and are as per the JS Zwave spec for this device model.

My installation is:
Home Assistant 2023.7.2 Supervisor 2023.07.1 Operating System 10.3 Frontend 20230705.1 - latest
running on an Odroid M1 + SSD [which works beautifully, is fast - and is now offically HA supported! Great.]
Add-ons: Z-Wave JS, Studio Code Server.
No Automations, etc… yet.

Solved : I used HA’s Developer Tools / Services with Service = Z-Wave: Reset meters on a node.
Chose the relevant Z-Wave device and ran service. Needed to refresh HA UI for reading to update, but power consumption was reset to 0 as required.
