***********************snipped******************************

• This behavior is only seen when start field of the range is updated.

Environment

• VMware NSX-T Data Center

• NSX version is 3.x/4.x

Cause

• When the start of a range is updated, all allocated ids must be remapped to new partitions. This remapping is not supported if the pool has allocated IDs. 

Resolution

• This is an expected behavior in all NSX versions.
