The "Update Network Resource Location" task is not assigning computers to the desired location, based on the subnets assigned to the computers.
This is a product defect, Etrack 2757979.
This can occur if computers have more than one IP Address and Subnet assigned.
This could be caused by having a wired and wireless NIC in the same system, a wired and or wireless NIC and virtual NIC from a VPN, a wired and or wireless NIC and VMWare or other similar tool, etc.
The code will only look at the max IP Address of the system.
This issue is expected to be resolved in a future version of CMDB Solution 7.x
