Cause
This happens if MPLS was installed and then uninstalled leaving some left-over files including mpls-backup.properties and msmpls-backup.properties.
Fix
Delete the two files under below directories:
Linux:
/var/opt/OV/shared/nnm/mpls-backup.properties
/var/opt/OV/shared/nnm/msmpls-backup.properties
Windows:
%NNMDataDir%\shared\nnm\mpls-backup.properties
%NNMDataDir%\shared\nnm\msmpls-backup.properties
