In some cases if the "HA Failover Detection Time Multiplier" is changed from the VCO, the change is not reflected in the edge config and the CLI is still showing the old value.
The feature is available starting version 5.2 so if the edge is on older version the change will not be applied even if it is saved successfully on the VCO.
Upgrade edge to any version starting 5.2 or higher
More info about changing the "HA Failover Detection Time Multiplier" can be found in the below documentation.
