Anyone know the methodology behind filing a PPSA?

Reason I ask is because I recently did a lien search against myself, and found that there is a PPSA against me (which I expected) for the car that I am currently leasing.

My problem is, my car lease is 5 years, but the PPSA is registered to end after 6 years, exactly one year after my lease is over.

Does this make sense, or did somebody screw up when registering this PPSA?
