The issue is caused by similar, already existing vLAN id's with the same environment. For example, existing Portgroup with vLANIDs:1000 / 413 / 150
- Creating a new Portgroup with VLAN ID 1 >> Summary will show VLAN ID value of 150
- Creating a new Portgroup with VLAN ID 100 >> Summary will show VLAN ID value of 1000
- Creating a new Portgroup with VLAN ID 4 >> Summary will show VLAN ID value of 413
- Creating a new Portgroup with VLAN ID 41 >> Summary will show VLAN ID value of 413
