Attempted PCEP Update for a non-delegated LSP throws error type 6 and value 14

PCEP update complains about missing symbolic path name (error type 6 and value 14) after delegation of the tunnel is revoked. The symbolic path name is learnt by the controller through REST even after delegation is revoked.

Snapshot of controllers REST output:
